Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537974, here are decompositions:
- 53 + 31537921 = 31537974
- 71 + 31537903 = 31537974
- 103 + 31537871 = 31537974
- 113 + 31537861 = 31537974
- 131 + 31537843 = 31537974
- 137 + 31537837 = 31537974
- 151 + 31537823 = 31537974
- 227 + 31537747 = 31537974
Showing the first eight; more decompositions exist.
