Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 632, here are decompositions:
- 13 + 619 = 632
- 19 + 613 = 632
- 31 + 601 = 632
- 61 + 571 = 632
- 109 + 523 = 632
- 193 + 439 = 632
- 199 + 433 = 632
- 211 + 421 = 632
Showing the first eight; more decompositions exist.
