Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503362, here are decompositions:

19 + 31503343 = 31503362
31 + 31503331 = 31503362
103 + 31503259 = 31503362
181 + 31503181 = 31503362
211 + 31503151 = 31503362
223 + 31503139 = 31503362
409 + 31502953 = 31503362
421 + 31502941 = 31503362

Showing the first eight; more decompositions exist.
