Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503832, here are decompositions:

23 + 31503809 = 31503832
53 + 31503779 = 31503832
83 + 31503749 = 31503832
263 + 31503569 = 31503832
389 + 31503443 = 31503832
491 + 31503341 = 31503832
509 + 31503323 = 31503832
653 + 31503179 = 31503832

Showing the first eight; more decompositions exist.
