Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541984, here are decompositions:
- 3 + 31541981 = 31541984
- 7 + 31541977 = 31541984
- 13 + 31541971 = 31541984
- 127 + 31541857 = 31541984
- 157 + 31541827 = 31541984
- 223 + 31541761 = 31541984
- 277 + 31541707 = 31541984
- 307 + 31541677 = 31541984
Showing the first eight; more decompositions exist.
