Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525536, here are decompositions:
- 37 + 31525499 = 31525536
- 47 + 31525489 = 31525536
- 59 + 31525477 = 31525536
- 89 + 31525447 = 31525536
- 139 + 31525397 = 31525536
- 157 + 31525379 = 31525536
- 193 + 31525343 = 31525536
- 257 + 31525279 = 31525536
Showing the first eight; more decompositions exist.
