Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179490, here are decompositions:

7 + 179483 = 179490
11 + 179479 = 179490
19 + 179471 = 179490
29 + 179461 = 179490
37 + 179453 = 179490
53 + 179437 = 179490
61 + 179429 = 179490
79 + 179411 = 179490

Showing the first eight; more decompositions exist.
