Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37990, here are decompositions:
- 3 + 37987 = 37990
- 23 + 37967 = 37990
- 83 + 37907 = 37990
- 101 + 37889 = 37990
- 137 + 37853 = 37990
- 179 + 37811 = 37990
- 191 + 37799 = 37990
- 347 + 37643 = 37990
Showing the first eight; more decompositions exist.
