Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577364, here are decompositions:
- 11 + 31577353 = 31577364
- 41 + 31577323 = 31577364
- 73 + 31577291 = 31577364
- 101 + 31577263 = 31577364
- 103 + 31577261 = 31577364
- 131 + 31577233 = 31577364
- 167 + 31577197 = 31577364
- 191 + 31577173 = 31577364
Showing the first eight; more decompositions exist.
