Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172718, here are decompositions:
- 31 + 172687 = 172718
- 37 + 172681 = 172718
- 61 + 172657 = 172718
- 157 + 172561 = 172718
- 199 + 172519 = 172718
- 211 + 172507 = 172718
- 229 + 172489 = 172718
- 277 + 172441 = 172718
Showing the first eight; more decompositions exist.
