Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492684, here are decompositions:
- 17 + 31492667 = 31492684
- 107 + 31492577 = 31492684
- 131 + 31492553 = 31492684
- 191 + 31492493 = 31492684
- 263 + 31492421 = 31492684
- 281 + 31492403 = 31492684
- 347 + 31492337 = 31492684
- 521 + 31492163 = 31492684
Showing the first eight; more decompositions exist.
