Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177638, here are decompositions:
- 37 + 177601 = 177638
- 127 + 177511 = 177638
- 151 + 177487 = 177638
- 157 + 177481 = 177638
- 211 + 177427 = 177638
- 229 + 177409 = 177638
- 337 + 177301 = 177638
- 421 + 177217 = 177638
Showing the first eight; more decompositions exist.
