Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524, here are decompositions:
- 3 + 521 = 524
- 37 + 487 = 524
- 61 + 463 = 524
- 67 + 457 = 524
- 103 + 421 = 524
- 127 + 397 = 524
- 151 + 373 = 524
- 157 + 367 = 524
Showing the first eight; more decompositions exist.
