Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77630, here are decompositions:
- 13 + 77617 = 77630
- 19 + 77611 = 77630
- 43 + 77587 = 77630
- 61 + 77569 = 77630
- 67 + 77563 = 77630
- 73 + 77557 = 77630
- 79 + 77551 = 77630
- 103 + 77527 = 77630
Showing the first eight; more decompositions exist.
