Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66602, here are decompositions:
- 31 + 66571 = 66602
- 61 + 66541 = 66602
- 73 + 66529 = 66602
- 79 + 66523 = 66602
- 103 + 66499 = 66602
- 139 + 66463 = 66602
- 199 + 66403 = 66602
- 229 + 66373 = 66602
Showing the first eight; more decompositions exist.
