Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450586, here are decompositions:
- 3 + 31450583 = 31450586
- 7 + 31450579 = 31450586
- 43 + 31450543 = 31450586
- 103 + 31450483 = 31450586
- 157 + 31450429 = 31450586
- 163 + 31450423 = 31450586
- 199 + 31450387 = 31450586
- 367 + 31450219 = 31450586
Showing the first eight; more decompositions exist.
