Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537250, here are decompositions:
- 7 + 31537243 = 31537250
- 97 + 31537153 = 31537250
- 103 + 31537147 = 31537250
- 163 + 31537087 = 31537250
- 211 + 31537039 = 31537250
- 223 + 31537027 = 31537250
- 307 + 31536943 = 31537250
- 313 + 31536937 = 31537250
Showing the first eight; more decompositions exist.
