Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39564, here are decompositions:
- 13 + 39551 = 39564
- 23 + 39541 = 39564
- 43 + 39521 = 39564
- 53 + 39511 = 39564
- 61 + 39503 = 39564
- 103 + 39461 = 39564
- 113 + 39451 = 39564
- 167 + 39397 = 39564
Showing the first eight; more decompositions exist.
