Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560064, here are decompositions:
- 5 + 31560059 = 31560064
- 17 + 31560047 = 31560064
- 83 + 31559981 = 31560064
- 113 + 31559951 = 31560064
- 233 + 31559831 = 31560064
- 251 + 31559813 = 31560064
- 281 + 31559783 = 31560064
- 293 + 31559771 = 31560064
Showing the first eight; more decompositions exist.
