Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516992, here are decompositions:
- 11 + 31516981 = 31516992
- 19 + 31516973 = 31516992
- 41 + 31516951 = 31516992
- 103 + 31516889 = 31516992
- 113 + 31516879 = 31516992
- 151 + 31516841 = 31516992
- 173 + 31516819 = 31516992
- 181 + 31516811 = 31516992
Showing the first eight; more decompositions exist.
