Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503292, here are decompositions:

83 + 31503209 = 31503292
89 + 31503203 = 31503292
113 + 31503179 = 31503292
173 + 31503119 = 31503292
239 + 31503053 = 31503292
593 + 31502699 = 31503292
809 + 31502483 = 31503292
929 + 31502363 = 31503292

Showing the first eight; more decompositions exist.
