Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503202, here are decompositions:

23 + 31503179 = 31503202
83 + 31503119 = 31503202
149 + 31503053 = 31503202
239 + 31502963 = 31503202
503 + 31502699 = 31503202
641 + 31502561 = 31503202
719 + 31502483 = 31503202
743 + 31502459 = 31503202

Showing the first eight; more decompositions exist.
