Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592160, here are decompositions:
- 11 + 31592149 = 31592160
- 31 + 31592129 = 31592160
- 37 + 31592123 = 31592160
- 107 + 31592053 = 31592160
- 109 + 31592051 = 31592160
- 113 + 31592047 = 31592160
- 163 + 31591997 = 31592160
- 167 + 31591993 = 31592160
Showing the first eight; more decompositions exist.
