Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66522, here are decompositions:
- 13 + 66509 = 66522
- 23 + 66499 = 66522
- 31 + 66491 = 66522
- 59 + 66463 = 66522
- 73 + 66449 = 66522
- 109 + 66413 = 66522
- 139 + 66383 = 66522
- 149 + 66373 = 66522
Showing the first eight; more decompositions exist.
