Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564004, here are decompositions:

37 + 31563967 = 31564004
61 + 31563943 = 31564004
67 + 31563937 = 31564004
97 + 31563907 = 31564004
127 + 31563877 = 31564004
211 + 31563793 = 31564004
271 + 31563733 = 31564004
541 + 31563463 = 31564004

Showing the first eight; more decompositions exist.
