Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503462, here are decompositions:

19 + 31503443 = 31503462
83 + 31503379 = 31503462
101 + 31503361 = 31503462
131 + 31503331 = 31503462
139 + 31503323 = 31503462
149 + 31503313 = 31503462
233 + 31503229 = 31503462
281 + 31503181 = 31503462

Showing the first eight; more decompositions exist.
