Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61664, here are decompositions:
- 7 + 61657 = 61664
- 13 + 61651 = 61664
- 37 + 61627 = 61664
- 61 + 61603 = 61664
- 103 + 61561 = 61664
- 157 + 61507 = 61664
- 181 + 61483 = 61664
- 193 + 61471 = 61664
Showing the first eight; more decompositions exist.
