Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2534, here are decompositions:
- 3 + 2531 = 2534
- 13 + 2521 = 2534
- 31 + 2503 = 2534
- 61 + 2473 = 2534
- 67 + 2467 = 2534
- 97 + 2437 = 2534
- 151 + 2383 = 2534
- 157 + 2377 = 2534
Showing the first eight; more decompositions exist.
