Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522590, here are decompositions:
- 7 + 31522583 = 31522590
- 37 + 31522553 = 31522590
- 41 + 31522549 = 31522590
- 61 + 31522529 = 31522590
- 67 + 31522523 = 31522590
- 97 + 31522493 = 31522590
- 131 + 31522459 = 31522590
- 139 + 31522451 = 31522590
Showing the first eight; more decompositions exist.
