Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503342, here are decompositions:

5 + 31503337 = 31503342
11 + 31503331 = 31503342
19 + 31503323 = 31503342
29 + 31503313 = 31503342
83 + 31503259 = 31503342
113 + 31503229 = 31503342
139 + 31503203 = 31503342
163 + 31503179 = 31503342

Showing the first eight; more decompositions exist.
