Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603040, here are decompositions:
- 13 + 31603027 = 31603040
- 31 + 31603009 = 31603040
- 67 + 31602973 = 31603040
- 109 + 31602931 = 31603040
- 163 + 31602877 = 31603040
- 181 + 31602859 = 31603040
- 277 + 31602763 = 31603040
- 349 + 31602691 = 31603040
Showing the first eight; more decompositions exist.
