Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160688, here are decompositions:
- 7 + 160681 = 160688
- 19 + 160669 = 160688
- 37 + 160651 = 160688
- 61 + 160627 = 160688
- 67 + 160621 = 160688
- 97 + 160591 = 160688
- 109 + 160579 = 160688
- 181 + 160507 = 160688
Showing the first eight; more decompositions exist.
