Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177624, here are decompositions:
- 23 + 177601 = 177624
- 71 + 177553 = 177624
- 113 + 177511 = 177624
- 131 + 177493 = 177624
- 137 + 177487 = 177624
- 151 + 177473 = 177624
- 157 + 177467 = 177624
- 191 + 177433 = 177624
Showing the first eight; more decompositions exist.
