Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38520, here are decompositions:
- 19 + 38501 = 38520
- 59 + 38461 = 38520
- 61 + 38459 = 38520
- 67 + 38453 = 38520
- 71 + 38449 = 38520
- 73 + 38447 = 38520
- 89 + 38431 = 38520
- 127 + 38393 = 38520
Showing the first eight; more decompositions exist.
