Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528004, here are decompositions:

3 + 31528001 = 31528004
7 + 31527997 = 31528004
37 + 31527967 = 31528004
73 + 31527931 = 31528004
223 + 31527781 = 31528004
307 + 31527697 = 31528004
421 + 31527583 = 31528004
463 + 31527541 = 31528004

Showing the first eight; more decompositions exist.
