Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77618, here are decompositions:
- 7 + 77611 = 77618
- 31 + 77587 = 77618
- 61 + 77557 = 77618
- 67 + 77551 = 77618
- 97 + 77521 = 77618
- 109 + 77509 = 77618
- 127 + 77491 = 77618
- 139 + 77479 = 77618
Showing the first eight; more decompositions exist.
