Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503302, here are decompositions:

43 + 31503259 = 31503302
73 + 31503229 = 31503302
151 + 31503151 = 31503302
163 + 31503139 = 31503302
199 + 31503103 = 31503302
241 + 31503061 = 31503302
349 + 31502953 = 31503302
379 + 31502923 = 31503302

Showing the first eight; more decompositions exist.
