Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638004, here are decompositions:

13 + 8637991 = 8638004
31 + 8637973 = 8638004
61 + 8637943 = 8638004
157 + 8637847 = 8638004
307 + 8637697 = 8638004
337 + 8637667 = 8638004
367 + 8637637 = 8638004
523 + 8637481 = 8638004

Showing the first eight; more decompositions exist.
