Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536, here are decompositions:
- 13 + 523 = 536
- 37 + 499 = 536
- 73 + 463 = 536
- 79 + 457 = 536
- 97 + 439 = 536
- 103 + 433 = 536
- 127 + 409 = 536
- 139 + 397 = 536
Showing the first eight; more decompositions exist.
