Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71570, here are decompositions:
- 7 + 71563 = 71570
- 19 + 71551 = 71570
- 43 + 71527 = 71570
- 67 + 71503 = 71570
- 97 + 71473 = 71570
- 127 + 71443 = 71570
- 151 + 71419 = 71570
- 157 + 71413 = 71570
Showing the first eight; more decompositions exist.
