Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579052, here are decompositions:

13 + 31579039 = 31579052
79 + 31578973 = 31579052
103 + 31578949 = 31579052
331 + 31578721 = 31579052
523 + 31578529 = 31579052
601 + 31578451 = 31579052
613 + 31578439 = 31579052
643 + 31578409 = 31579052

Showing the first eight; more decompositions exist.
