Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503844, here are decompositions:

3 + 31503841 = 31503844
131 + 31503713 = 31503844
401 + 31503443 = 31503844
503 + 31503341 = 31503844
521 + 31503323 = 31503844
641 + 31503203 = 31503844
677 + 31503167 = 31503844
881 + 31502963 = 31503844

Showing the first eight; more decompositions exist.
