Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80586, here are decompositions:
- 19 + 80567 = 80586
- 29 + 80557 = 80586
- 59 + 80527 = 80586
- 73 + 80513 = 80586
- 97 + 80489 = 80586
- 113 + 80473 = 80586
- 137 + 80449 = 80586
- 139 + 80447 = 80586
Showing the first eight; more decompositions exist.
