Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496042, here are decompositions:

31 + 31496011 = 31496042
163 + 31495879 = 31496042
223 + 31495819 = 31496042
241 + 31495801 = 31496042
313 + 31495729 = 31496042
349 + 31495693 = 31496042
379 + 31495663 = 31496042
439 + 31495603 = 31496042

Showing the first eight; more decompositions exist.
