Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520062, here are decompositions:

3 + 31520059 = 31520062
53 + 31520009 = 31520062
173 + 31519889 = 31520062
239 + 31519823 = 31520062
269 + 31519793 = 31520062
293 + 31519769 = 31520062
359 + 31519703 = 31520062
383 + 31519679 = 31520062

Showing the first eight; more decompositions exist.
