Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71622, here are decompositions:
- 29 + 71593 = 71622
- 53 + 71569 = 71622
- 59 + 71563 = 71622
- 71 + 71551 = 71622
- 73 + 71549 = 71622
- 139 + 71483 = 71622
- 149 + 71473 = 71622
- 151 + 71471 = 71622
Showing the first eight; more decompositions exist.
