Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77712, here are decompositions:
- 13 + 77699 = 77712
- 23 + 77689 = 77712
- 31 + 77681 = 77712
- 53 + 77659 = 77712
- 71 + 77641 = 77712
- 101 + 77611 = 77712
- 139 + 77573 = 77712
- 149 + 77563 = 77712
Showing the first eight; more decompositions exist.
