Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77490, here are decompositions:
- 11 + 77479 = 77490
- 13 + 77477 = 77490
- 19 + 77471 = 77490
- 43 + 77447 = 77490
- 59 + 77431 = 77490
- 71 + 77419 = 77490
- 73 + 77417 = 77490
- 107 + 77383 = 77490
Showing the first eight; more decompositions exist.
