Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576502, here are decompositions:
- 19 + 31576483 = 31576502
- 43 + 31576459 = 31576502
- 151 + 31576351 = 31576502
- 241 + 31576261 = 31576502
- 271 + 31576231 = 31576502
- 283 + 31576219 = 31576502
- 499 + 31576003 = 31576502
- 673 + 31575829 = 31576502
Showing the first eight; more decompositions exist.
