Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80658, here are decompositions:

7 + 80651 = 80658
29 + 80629 = 80658
31 + 80627 = 80658
37 + 80621 = 80658
47 + 80611 = 80658
59 + 80599 = 80658
101 + 80557 = 80658
131 + 80527 = 80658

Showing the first eight; more decompositions exist.
