Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3542, here are decompositions:
- 3 + 3539 = 3542
- 13 + 3529 = 3542
- 31 + 3511 = 3542
- 43 + 3499 = 3542
- 73 + 3469 = 3542
- 79 + 3463 = 3542
- 109 + 3433 = 3542
- 151 + 3391 = 3542
Showing the first eight; more decompositions exist.
