Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503952, here are decompositions:

23 + 31503929 = 31503952
41 + 31503911 = 31503952
89 + 31503863 = 31503952
173 + 31503779 = 31503952
239 + 31503713 = 31503952
383 + 31503569 = 31503952
443 + 31503509 = 31503952
509 + 31503443 = 31503952

Showing the first eight; more decompositions exist.
