Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37998, here are decompositions:
- 5 + 37993 = 37998
- 7 + 37991 = 37998
- 11 + 37987 = 37998
- 31 + 37967 = 37998
- 41 + 37957 = 37998
- 47 + 37951 = 37998
- 101 + 37897 = 37998
- 109 + 37889 = 37998
Showing the first eight; more decompositions exist.
