Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71582, here are decompositions:
- 13 + 71569 = 71582
- 19 + 71563 = 71582
- 31 + 71551 = 71582
- 79 + 71503 = 71582
- 103 + 71479 = 71582
- 109 + 71473 = 71582
- 139 + 71443 = 71582
- 163 + 71419 = 71582
Showing the first eight; more decompositions exist.
