Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528602, here are decompositions:
- 23 + 31528579 = 31528602
- 29 + 31528573 = 31528602
- 43 + 31528559 = 31528602
- 71 + 31528531 = 31528602
- 101 + 31528501 = 31528602
- 103 + 31528499 = 31528602
- 151 + 31528451 = 31528602
- 229 + 31528373 = 31528602
Showing the first eight; more decompositions exist.
