Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503892, here are decompositions:

5 + 31503887 = 31503892
29 + 31503863 = 31503892
83 + 31503809 = 31503892
113 + 31503779 = 31503892
179 + 31503713 = 31503892
383 + 31503509 = 31503892
449 + 31503443 = 31503892
569 + 31503323 = 31503892

Showing the first eight; more decompositions exist.
