Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503104, here are decompositions:

43 + 31503061 = 31503104
151 + 31502953 = 31503104
163 + 31502941 = 31503104
181 + 31502923 = 31503104
223 + 31502881 = 31503104
541 + 31502563 = 31503104
547 + 31502557 = 31503104
571 + 31502533 = 31503104

Showing the first eight; more decompositions exist.
