Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537726, here are decompositions:
- 5 + 31537721 = 31537726
- 167 + 31537559 = 31537726
- 179 + 31537547 = 31537726
- 257 + 31537469 = 31537726
- 293 + 31537433 = 31537726
- 317 + 31537409 = 31537726
- 419 + 31537307 = 31537726
- 503 + 31537223 = 31537726
Showing the first eight; more decompositions exist.
