Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27578, here are decompositions:
- 37 + 27541 = 27578
- 97 + 27481 = 27578
- 151 + 27427 = 27578
- 181 + 27397 = 27578
- 211 + 27367 = 27578
- 241 + 27337 = 27578
- 307 + 27271 = 27578
- 337 + 27241 = 27578
Showing the first eight; more decompositions exist.
