Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177508, here are decompositions:
- 41 + 177467 = 177508
- 239 + 177269 = 177508
- 251 + 177257 = 177508
- 269 + 177239 = 177508
- 557 + 176951 = 177508
- 587 + 176921 = 177508
- 659 + 176849 = 177508
- 701 + 176807 = 177508
Showing the first eight; more decompositions exist.
