Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71562, here are decompositions:
- 11 + 71551 = 71562
- 13 + 71549 = 71562
- 59 + 71503 = 71562
- 79 + 71483 = 71562
- 83 + 71479 = 71562
- 89 + 71473 = 71562
- 109 + 71453 = 71562
- 149 + 71413 = 71562
Showing the first eight; more decompositions exist.
