Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38490, here are decompositions:
- 29 + 38461 = 38490
- 31 + 38459 = 38490
- 37 + 38453 = 38490
- 41 + 38449 = 38490
- 43 + 38447 = 38490
- 59 + 38431 = 38490
- 97 + 38393 = 38490
- 113 + 38377 = 38490
Showing the first eight; more decompositions exist.
