Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77672, here are decompositions:
- 13 + 77659 = 77672
- 31 + 77641 = 77672
- 61 + 77611 = 77672
- 103 + 77569 = 77672
- 109 + 77563 = 77672
- 151 + 77521 = 77672
- 163 + 77509 = 77672
- 181 + 77491 = 77672
Showing the first eight; more decompositions exist.
