Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603520, here are decompositions:
- 31 + 31603489 = 31603520
- 127 + 31603393 = 31603520
- 139 + 31603381 = 31603520
- 211 + 31603309 = 31603520
- 271 + 31603249 = 31603520
- 373 + 31603147 = 31603520
- 379 + 31603141 = 31603520
- 397 + 31603123 = 31603520
Showing the first eight; more decompositions exist.
