Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76440, here are decompositions:
- 17 + 76423 = 76440
- 19 + 76421 = 76440
- 37 + 76403 = 76440
- 53 + 76387 = 76440
- 61 + 76379 = 76440
- 71 + 76369 = 76440
- 73 + 76367 = 76440
- 97 + 76343 = 76440
Showing the first eight; more decompositions exist.
