Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172752, here are decompositions:
- 11 + 172741 = 172752
- 31 + 172721 = 172752
- 43 + 172709 = 172752
- 71 + 172681 = 172752
- 79 + 172673 = 172752
- 89 + 172663 = 172752
- 103 + 172649 = 172752
- 109 + 172643 = 172752
Showing the first eight; more decompositions exist.
