Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 534, here are decompositions:
- 11 + 523 = 534
- 13 + 521 = 534
- 31 + 503 = 534
- 43 + 491 = 534
- 47 + 487 = 534
- 67 + 467 = 534
- 71 + 463 = 534
- 73 + 461 = 534
Showing the first eight; more decompositions exist.
