Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71538, here are decompositions:
- 11 + 71527 = 71538
- 59 + 71479 = 71538
- 67 + 71471 = 71538
- 101 + 71437 = 71538
- 109 + 71429 = 71538
- 127 + 71411 = 71538
- 139 + 71399 = 71538
- 149 + 71389 = 71538
Showing the first eight; more decompositions exist.
