Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 546, here are decompositions:
- 5 + 541 = 546
- 23 + 523 = 546
- 37 + 509 = 546
- 43 + 503 = 546
- 47 + 499 = 546
- 59 + 487 = 546
- 67 + 479 = 546
- 79 + 467 = 546
Showing the first eight; more decompositions exist.
