Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63506, here are decompositions:
- 7 + 63499 = 63506
- 13 + 63493 = 63506
- 19 + 63487 = 63506
- 43 + 63463 = 63506
- 67 + 63439 = 63506
- 97 + 63409 = 63506
- 109 + 63397 = 63506
- 139 + 63367 = 63506
Showing the first eight; more decompositions exist.
