Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151736, here are decompositions:
- 3 + 151733 = 151736
- 7 + 151729 = 151736
- 19 + 151717 = 151736
- 43 + 151693 = 151736
- 127 + 151609 = 151736
- 139 + 151597 = 151736
- 157 + 151579 = 151736
- 163 + 151573 = 151736
Showing the first eight; more decompositions exist.
