Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503096, here are decompositions:

43 + 31503053 = 31503096
103 + 31502993 = 31503096
137 + 31502959 = 31503096
173 + 31502923 = 31503096
199 + 31502897 = 31503096
239 + 31502857 = 31503096
353 + 31502743 = 31503096
397 + 31502699 = 31503096

Showing the first eight; more decompositions exist.
