Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7836, here are decompositions:
- 7 + 7829 = 7836
- 13 + 7823 = 7836
- 19 + 7817 = 7836
- 43 + 7793 = 7836
- 47 + 7789 = 7836
- 79 + 7757 = 7836
- 83 + 7753 = 7836
- 109 + 7727 = 7836
Showing the first eight; more decompositions exist.
