Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503322, here are decompositions:

113 + 31503209 = 31503322
269 + 31503053 = 31503322
359 + 31502963 = 31503322
761 + 31502561 = 31503322
839 + 31502483 = 31503322
863 + 31502459 = 31503322
881 + 31502441 = 31503322
1109 + 31502213 = 31503322

Showing the first eight; more decompositions exist.
