Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515526, here are decompositions:
- 113 + 31515413 = 31515526
- 137 + 31515389 = 31515526
- 149 + 31515377 = 31515526
- 173 + 31515353 = 31515526
- 227 + 31515299 = 31515526
- 239 + 31515287 = 31515526
- 257 + 31515269 = 31515526
- 347 + 31515179 = 31515526
Showing the first eight; more decompositions exist.
