Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489526, here are decompositions:
- 7 + 31489519 = 31489526
- 37 + 31489489 = 31489526
- 109 + 31489417 = 31489526
- 127 + 31489399 = 31489526
- 163 + 31489363 = 31489526
- 283 + 31489243 = 31489526
- 349 + 31489177 = 31489526
- 379 + 31489147 = 31489526
Showing the first eight; more decompositions exist.
