Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80490, here are decompositions:

17 + 80473 = 80490
19 + 80471 = 80490
41 + 80449 = 80490
43 + 80447 = 80490
61 + 80429 = 80490
83 + 80407 = 80490
103 + 80387 = 80490
127 + 80363 = 80490

Showing the first eight; more decompositions exist.
