Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496000, here are decompositions:

79 + 31495921 = 31496000
103 + 31495897 = 31496000
181 + 31495819 = 31496000
199 + 31495801 = 31496000
271 + 31495729 = 31496000
307 + 31495693 = 31496000
337 + 31495663 = 31496000
397 + 31495603 = 31496000

Showing the first eight; more decompositions exist.
