Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37638, here are decompositions:
- 5 + 37633 = 37638
- 19 + 37619 = 37638
- 31 + 37607 = 37638
- 47 + 37591 = 37638
- 59 + 37579 = 37638
- 67 + 37571 = 37638
- 71 + 37567 = 37638
- 89 + 37549 = 37638
Showing the first eight; more decompositions exist.
