Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599490, here are decompositions:
- 3 + 31599487 = 31599490
- 59 + 31599431 = 31599490
- 101 + 31599389 = 31599490
- 137 + 31599353 = 31599490
- 149 + 31599341 = 31599490
- 317 + 31599173 = 31599490
- 389 + 31599101 = 31599490
- 431 + 31599059 = 31599490
Showing the first eight; more decompositions exist.
