Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27512, here are decompositions:
- 3 + 27509 = 27512
- 31 + 27481 = 27512
- 103 + 27409 = 27512
- 151 + 27361 = 27512
- 229 + 27283 = 27512
- 241 + 27271 = 27512
- 271 + 27241 = 27512
- 409 + 27103 = 27512
Showing the first eight; more decompositions exist.
