Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537506, here are decompositions:
- 29 + 31537477 = 31537506
- 37 + 31537469 = 31537506
- 73 + 31537433 = 31537506
- 97 + 31537409 = 31537506
- 167 + 31537339 = 31537506
- 179 + 31537327 = 31537506
- 193 + 31537313 = 31537506
- 197 + 31537309 = 31537506
Showing the first eight; more decompositions exist.
