Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536634, here are decompositions:
- 5 + 31536629 = 31536634
- 83 + 31536551 = 31536634
- 113 + 31536521 = 31536634
- 251 + 31536383 = 31536634
- 281 + 31536353 = 31536634
- 347 + 31536287 = 31536634
- 431 + 31536203 = 31536634
- 617 + 31536017 = 31536634
Showing the first eight; more decompositions exist.
