Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85744, here are decompositions:
- 11 + 85733 = 85744
- 41 + 85703 = 85744
- 53 + 85691 = 85744
- 83 + 85661 = 85744
- 101 + 85643 = 85744
- 137 + 85607 = 85744
- 167 + 85577 = 85744
- 173 + 85571 = 85744
Showing the first eight; more decompositions exist.
