Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503304, here are decompositions:

101 + 31503203 = 31503304
137 + 31503167 = 31503304
197 + 31503107 = 31503304
251 + 31503053 = 31503304
311 + 31502993 = 31503304
617 + 31502687 = 31503304
743 + 31502561 = 31503304
821 + 31502483 = 31503304

Showing the first eight; more decompositions exist.
