Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572370, here are decompositions:
- 23 + 31572347 = 31572370
- 29 + 31572341 = 31572370
- 47 + 31572323 = 31572370
- 107 + 31572263 = 31572370
- 149 + 31572221 = 31572370
- 227 + 31572143 = 31572370
- 239 + 31572131 = 31572370
- 311 + 31572059 = 31572370
Showing the first eight; more decompositions exist.
