Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77578, here are decompositions:
- 5 + 77573 = 77578
- 29 + 77549 = 77578
- 89 + 77489 = 77578
- 101 + 77477 = 77578
- 107 + 77471 = 77578
- 131 + 77447 = 77578
- 227 + 77351 = 77578
- 239 + 77339 = 77578
Showing the first eight; more decompositions exist.
