Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37720, here are decompositions:
- 3 + 37717 = 37720
- 29 + 37691 = 37720
- 71 + 37649 = 37720
- 101 + 37619 = 37720
- 113 + 37607 = 37720
- 131 + 37589 = 37720
- 149 + 37571 = 37720
- 173 + 37547 = 37720
Showing the first eight; more decompositions exist.
