Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77478, here are decompositions:
- 7 + 77471 = 77478
- 31 + 77447 = 77478
- 47 + 77431 = 77478
- 59 + 77419 = 77478
- 61 + 77417 = 77478
- 101 + 77377 = 77478
- 109 + 77369 = 77478
- 127 + 77351 = 77478
Showing the first eight; more decompositions exist.
