Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159540, here are decompositions:
- 19 + 159521 = 159540
- 37 + 159503 = 159540
- 41 + 159499 = 159540
- 67 + 159473 = 159540
- 71 + 159469 = 159540
- 83 + 159457 = 159540
- 103 + 159437 = 159540
- 109 + 159431 = 159540
Showing the first eight; more decompositions exist.
