Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563536, here are decompositions:

73 + 31563463 = 31563536
283 + 31563253 = 31563536
349 + 31563187 = 31563536
373 + 31563163 = 31563536
409 + 31563127 = 31563536
463 + 31563073 = 31563536
523 + 31563013 = 31563536
577 + 31562959 = 31563536

Showing the first eight; more decompositions exist.
