Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564124, here are decompositions:

73 + 31564051 = 31564124
157 + 31563967 = 31564124
181 + 31563943 = 31564124
307 + 31563817 = 31564124
331 + 31563793 = 31564124
337 + 31563787 = 31564124
523 + 31563601 = 31564124
661 + 31563463 = 31564124

Showing the first eight; more decompositions exist.
