Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538124, here are decompositions:
- 11 + 31538113 = 31538124
- 17 + 31538107 = 31538124
- 53 + 31538071 = 31538124
- 61 + 31538063 = 31538124
- 71 + 31538053 = 31538124
- 127 + 31537997 = 31538124
- 263 + 31537861 = 31538124
- 281 + 31537843 = 31538124
Showing the first eight; more decompositions exist.
