Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71508, here are decompositions:
- 5 + 71503 = 71508
- 29 + 71479 = 71508
- 37 + 71471 = 71508
- 71 + 71437 = 71508
- 79 + 71429 = 71508
- 89 + 71419 = 71508
- 97 + 71411 = 71508
- 109 + 71399 = 71508
Showing the first eight; more decompositions exist.
