Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496182, here are decompositions:

41 + 31496141 = 31496182
59 + 31496123 = 31496182
83 + 31496099 = 31496182
233 + 31495949 = 31496182
449 + 31495733 = 31496182
491 + 31495691 = 31496182
521 + 31495661 = 31496182
593 + 31495589 = 31496182

Showing the first eight; more decompositions exist.
