Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39480, here are decompositions:
- 19 + 39461 = 39480
- 29 + 39451 = 39480
- 37 + 39443 = 39480
- 41 + 39439 = 39480
- 61 + 39419 = 39480
- 71 + 39409 = 39480
- 83 + 39397 = 39480
- 97 + 39383 = 39480
Showing the first eight; more decompositions exist.
