Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507056, here are decompositions:
- 19 + 31507037 = 31507056
- 47 + 31507009 = 31507056
- 79 + 31506977 = 31507056
- 83 + 31506973 = 31507056
- 107 + 31506949 = 31507056
- 127 + 31506929 = 31507056
- 149 + 31506907 = 31507056
- 227 + 31506829 = 31507056
Showing the first eight; more decompositions exist.
