Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532078, here are decompositions:
- 7 + 31532071 = 31532078
- 157 + 31531921 = 31532078
- 439 + 31531639 = 31532078
- 499 + 31531579 = 31532078
- 607 + 31531471 = 31532078
- 661 + 31531417 = 31532078
- 709 + 31531369 = 31532078
- 811 + 31531267 = 31532078
Showing the first eight; more decompositions exist.
