Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77520, here are decompositions:
- 7 + 77513 = 77520
- 11 + 77509 = 77520
- 29 + 77491 = 77520
- 31 + 77489 = 77520
- 41 + 77479 = 77520
- 43 + 77477 = 77520
- 73 + 77447 = 77520
- 89 + 77431 = 77520
Showing the first eight; more decompositions exist.
