Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71532, here are decompositions:
- 5 + 71527 = 71532
- 29 + 71503 = 71532
- 53 + 71479 = 71532
- 59 + 71473 = 71532
- 61 + 71471 = 71532
- 79 + 71453 = 71532
- 89 + 71443 = 71532
- 103 + 71429 = 71532
Showing the first eight; more decompositions exist.
