Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531202, here are decompositions:

103 + 31531099 = 31531202
139 + 31531063 = 31531202
223 + 31530979 = 31531202
229 + 31530973 = 31531202
499 + 31530703 = 31531202
523 + 31530679 = 31531202
541 + 31530661 = 31531202
613 + 31530589 = 31531202

Showing the first eight; more decompositions exist.
