Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496090, here are decompositions:

7 + 31496083 = 31496090
79 + 31496011 = 31496090
193 + 31495897 = 31496090
211 + 31495879 = 31496090
271 + 31495819 = 31496090
337 + 31495753 = 31496090
349 + 31495741 = 31496090
397 + 31495693 = 31496090

Showing the first eight; more decompositions exist.
