Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31012, here are decompositions:
- 29 + 30983 = 31012
- 41 + 30971 = 31012
- 71 + 30941 = 31012
- 101 + 30911 = 31012
- 131 + 30881 = 31012
- 173 + 30839 = 31012
- 239 + 30773 = 31012
- 419 + 30593 = 31012
Showing the first eight; more decompositions exist.
