Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38972, here are decompositions:
- 13 + 38959 = 38972
- 19 + 38953 = 38972
- 139 + 38833 = 38972
- 151 + 38821 = 38972
- 181 + 38791 = 38972
- 223 + 38749 = 38972
- 379 + 38593 = 38972
- 523 + 38449 = 38972
Showing the first eight; more decompositions exist.
