Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503198, here are decompositions:

17 + 31503181 = 31503198
19 + 31503179 = 31503198
31 + 31503167 = 31503198
47 + 31503151 = 31503198
59 + 31503139 = 31503198
79 + 31503119 = 31503198
137 + 31503061 = 31503198
239 + 31502959 = 31503198

Showing the first eight; more decompositions exist.
