Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505014, here are decompositions:

11 + 31505003 = 31505014
71 + 31504943 = 31505014
131 + 31504883 = 31505014
311 + 31504703 = 31505014
347 + 31504667 = 31505014
353 + 31504661 = 31505014
467 + 31504547 = 31505014
521 + 31504493 = 31505014

Showing the first eight; more decompositions exist.
