Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503272, here are decompositions:

13 + 31503259 = 31503272
43 + 31503229 = 31503272
211 + 31503061 = 31503272
313 + 31502959 = 31503272
331 + 31502941 = 31503272
349 + 31502923 = 31503272
571 + 31502701 = 31503272
613 + 31502659 = 31503272

Showing the first eight; more decompositions exist.
