Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151744, here are decompositions:
- 11 + 151733 = 151744
- 41 + 151703 = 151744
- 71 + 151673 = 151744
- 101 + 151643 = 151744
- 107 + 151637 = 151744
- 113 + 151631 = 151744
- 137 + 151607 = 151744
- 191 + 151553 = 151744
Showing the first eight; more decompositions exist.
