Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538006, here are decompositions:

7 + 31537999 = 31538006
67 + 31537939 = 31538006
103 + 31537903 = 31538006
163 + 31537843 = 31538006
397 + 31537609 = 31538006
433 + 31537573 = 31538006
463 + 31537543 = 31538006
499 + 31537507 = 31538006

Showing the first eight; more decompositions exist.
