Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61656, here are decompositions:
- 5 + 61651 = 61656
- 13 + 61643 = 61656
- 19 + 61637 = 61656
- 29 + 61627 = 61656
- 43 + 61613 = 61656
- 47 + 61609 = 61656
- 53 + 61603 = 61656
- 73 + 61583 = 61656
Showing the first eight; more decompositions exist.
