Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507498, here are decompositions:
- 131 + 31507367 = 31507498
- 137 + 31507361 = 31507498
- 179 + 31507319 = 31507498
- 227 + 31507271 = 31507498
- 317 + 31507181 = 31507498
- 359 + 31507139 = 31507498
- 389 + 31507109 = 31507498
- 461 + 31507037 = 31507498
Showing the first eight; more decompositions exist.
