Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71556, here are decompositions:
- 5 + 71551 = 71556
- 7 + 71549 = 71556
- 19 + 71537 = 71556
- 29 + 71527 = 71556
- 53 + 71503 = 71556
- 73 + 71483 = 71556
- 83 + 71473 = 71556
- 103 + 71453 = 71556
Showing the first eight; more decompositions exist.
