Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532496, here are decompositions:
- 7 + 31532489 = 31532496
- 19 + 31532477 = 31532496
- 59 + 31532437 = 31532496
- 67 + 31532429 = 31532496
- 157 + 31532339 = 31532496
- 167 + 31532329 = 31532496
- 173 + 31532323 = 31532496
- 227 + 31532269 = 31532496
Showing the first eight; more decompositions exist.
