Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671530, here are decompositions:
- 11 + 8671519 = 8671530
- 13 + 8671517 = 8671530
- 19 + 8671511 = 8671530
- 29 + 8671501 = 8671530
- 31 + 8671499 = 8671530
- 59 + 8671471 = 8671530
- 61 + 8671469 = 8671530
- 67 + 8671463 = 8671530
Showing the first eight; more decompositions exist.
