Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538056, here are decompositions:
- 3 + 31538053 = 31538056
- 23 + 31538033 = 31538056
- 59 + 31537997 = 31538056
- 167 + 31537889 = 31538056
- 197 + 31537859 = 31538056
- 233 + 31537823 = 31538056
- 509 + 31537547 = 31538056
- 587 + 31537469 = 31538056
Showing the first eight; more decompositions exist.
