Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77530, here are decompositions:
- 3 + 77527 = 77530
- 17 + 77513 = 77530
- 41 + 77489 = 77530
- 53 + 77477 = 77530
- 59 + 77471 = 77530
- 83 + 77447 = 77530
- 113 + 77417 = 77530
- 179 + 77351 = 77530
Showing the first eight; more decompositions exist.
