Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503182, here are decompositions:

3 + 31503179 = 31503182
31 + 31503151 = 31503182
43 + 31503139 = 31503182
79 + 31503103 = 31503182
223 + 31502959 = 31503182
229 + 31502953 = 31503182
241 + 31502941 = 31503182
421 + 31502761 = 31503182

Showing the first eight; more decompositions exist.
