Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508462, here are decompositions:

19 + 31508443 = 31508462
103 + 31508359 = 31508462
151 + 31508311 = 31508462
229 + 31508233 = 31508462
283 + 31508179 = 31508462
379 + 31508083 = 31508462
523 + 31507939 = 31508462
541 + 31507921 = 31508462

Showing the first eight; more decompositions exist.
