Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27572, here are decompositions:
- 31 + 27541 = 27572
- 43 + 27529 = 27572
- 163 + 27409 = 27572
- 211 + 27361 = 27572
- 313 + 27259 = 27572
- 331 + 27241 = 27572
- 463 + 27109 = 27572
- 499 + 27073 = 27572
Showing the first eight; more decompositions exist.
