Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27570, here are decompositions:
- 19 + 27551 = 27570
- 29 + 27541 = 27570
- 31 + 27539 = 27570
- 41 + 27529 = 27570
- 43 + 27527 = 27570
- 61 + 27509 = 27570
- 83 + 27487 = 27570
- 89 + 27481 = 27570
Showing the first eight; more decompositions exist.
