Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602988, here are decompositions:
- 29 + 31602959 = 31602988
- 71 + 31602917 = 31602988
- 89 + 31602899 = 31602988
- 401 + 31602587 = 31602988
- 449 + 31602539 = 31602988
- 467 + 31602521 = 31602988
- 491 + 31602497 = 31602988
- 587 + 31602401 = 31602988
Showing the first eight; more decompositions exist.
