Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1836, here are decompositions:
- 5 + 1831 = 1836
- 13 + 1823 = 1836
- 47 + 1789 = 1836
- 53 + 1783 = 1836
- 59 + 1777 = 1836
- 83 + 1753 = 1836
- 89 + 1747 = 1836
- 103 + 1733 = 1836
Showing the first eight; more decompositions exist.

The digit sequence 1836 first appears in π at position 8,982 of the decimal expansion (the 8,982ordinal-suffix:nd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
