Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71564, here are decompositions:
- 13 + 71551 = 71564
- 37 + 71527 = 71564
- 61 + 71503 = 71564
- 127 + 71437 = 71564
- 151 + 71413 = 71564
- 211 + 71353 = 71564
- 223 + 71341 = 71564
- 271 + 71293 = 71564
Showing the first eight; more decompositions exist.
