Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532392, here are decompositions:
- 53 + 31532339 = 31532392
- 113 + 31532279 = 31532392
- 131 + 31532261 = 31532392
- 173 + 31532219 = 31532392
- 251 + 31532141 = 31532392
- 389 + 31532003 = 31532392
- 461 + 31531931 = 31532392
- 509 + 31531883 = 31532392
Showing the first eight; more decompositions exist.
