Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53666, here are decompositions:
- 13 + 53653 = 53666
- 37 + 53629 = 53666
- 43 + 53623 = 53666
- 73 + 53593 = 53666
- 97 + 53569 = 53666
- 139 + 53527 = 53666
- 163 + 53503 = 53666
- 229 + 53437 = 53666
Showing the first eight; more decompositions exist.
