Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559924, here are decompositions:

13 + 31559911 = 31559924
73 + 31559851 = 31559924
103 + 31559821 = 31559924
271 + 31559653 = 31559924
283 + 31559641 = 31559924
457 + 31559467 = 31559924
523 + 31559401 = 31559924
541 + 31559383 = 31559924

Showing the first eight; more decompositions exist.
