Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534952, here are decompositions:

73 + 31534879 = 31534952
79 + 31534873 = 31534952
151 + 31534801 = 31534952
199 + 31534753 = 31534952
223 + 31534729 = 31534952
283 + 31534669 = 31534952
409 + 31534543 = 31534952
523 + 31534429 = 31534952

Showing the first eight; more decompositions exist.
