Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496020, here are decompositions:

41 + 31495979 = 31496020
71 + 31495949 = 31496020
173 + 31495847 = 31496020
263 + 31495757 = 31496020
359 + 31495661 = 31496020
419 + 31495601 = 31496020
431 + 31495589 = 31496020
503 + 31495517 = 31496020

Showing the first eight; more decompositions exist.
