Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609252, here are decompositions:
- 23 + 31609229 = 31609252
- 29 + 31609223 = 31609252
- 173 + 31609079 = 31609252
- 281 + 31608971 = 31609252
- 293 + 31608959 = 31609252
- 359 + 31608893 = 31609252
- 401 + 31608851 = 31609252
- 431 + 31608821 = 31609252
Showing the first eight; more decompositions exist.
