Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177582, here are decompositions:
- 29 + 177553 = 177582
- 43 + 177539 = 177582
- 71 + 177511 = 177582
- 89 + 177493 = 177582
- 101 + 177481 = 177582
- 109 + 177473 = 177582
- 149 + 177433 = 177582
- 151 + 177431 = 177582
Showing the first eight; more decompositions exist.
