Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638084, here are decompositions:

17 + 8638067 = 8638084
23 + 8638061 = 8638084
41 + 8638043 = 8638084
131 + 8637953 = 8638084
263 + 8637821 = 8638084
293 + 8637791 = 8638084
383 + 8637701 = 8638084
443 + 8637641 = 8638084

Showing the first eight; more decompositions exist.
