Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531052, here are decompositions:
- 73 + 31530979 = 31531052
- 79 + 31530973 = 31531052
- 109 + 31530943 = 31531052
- 151 + 31530901 = 31531052
- 211 + 31530841 = 31531052
- 349 + 31530703 = 31531052
- 373 + 31530679 = 31531052
- 409 + 31530643 = 31531052
Showing the first eight; more decompositions exist.
