Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619006, here are decompositions:

7 + 31618999 = 31619006
109 + 31618897 = 31619006
127 + 31618879 = 31619006
157 + 31618849 = 31619006
229 + 31618777 = 31619006
313 + 31618693 = 31619006
337 + 31618669 = 31619006
373 + 31618633 = 31619006

Showing the first eight; more decompositions exist.
