Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456084, here are decompositions:

5 + 31456079 = 31456084
17 + 31456067 = 31456084
71 + 31456013 = 31456084
137 + 31455947 = 31456084
263 + 31455821 = 31456084
281 + 31455803 = 31456084
383 + 31455701 = 31456084
461 + 31455623 = 31456084

Showing the first eight; more decompositions exist.
