Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31672, here are decompositions:
- 5 + 31667 = 31672
- 23 + 31649 = 31672
- 29 + 31643 = 31672
- 71 + 31601 = 31672
- 89 + 31583 = 31672
- 131 + 31541 = 31672
- 191 + 31481 = 31672
- 281 + 31391 = 31672
Showing the first eight; more decompositions exist.
