Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52640, here are decompositions:
- 13 + 52627 = 52640
- 31 + 52609 = 52640
- 61 + 52579 = 52640
- 73 + 52567 = 52640
- 79 + 52561 = 52640
- 97 + 52543 = 52640
- 139 + 52501 = 52640
- 151 + 52489 = 52640
Showing the first eight; more decompositions exist.
