Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538482, here are decompositions:
- 5 + 31538477 = 31538482
- 71 + 31538411 = 31538482
- 149 + 31538333 = 31538482
- 419 + 31538063 = 31538482
- 449 + 31538033 = 31538482
- 593 + 31537889 = 31538482
- 659 + 31537823 = 31538482
- 761 + 31537721 = 31538482
Showing the first eight; more decompositions exist.
