Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66624, here are decompositions:
- 7 + 66617 = 66624
- 23 + 66601 = 66624
- 31 + 66593 = 66624
- 37 + 66587 = 66624
- 53 + 66571 = 66624
- 71 + 66553 = 66624
- 83 + 66541 = 66624
- 101 + 66523 = 66624
Showing the first eight; more decompositions exist.
