Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71502, here are decompositions:
- 19 + 71483 = 71502
- 23 + 71479 = 71502
- 29 + 71473 = 71502
- 31 + 71471 = 71502
- 59 + 71443 = 71502
- 73 + 71429 = 71502
- 83 + 71419 = 71502
- 89 + 71413 = 71502
Showing the first eight; more decompositions exist.
