Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607038, here are decompositions:
- 41 + 31606997 = 31607038
- 59 + 31606979 = 31607038
- 107 + 31606931 = 31607038
- 191 + 31606847 = 31607038
- 227 + 31606811 = 31607038
- 311 + 31606727 = 31607038
- 347 + 31606691 = 31607038
- 479 + 31606559 = 31607038
Showing the first eight; more decompositions exist.
