Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538048, here are decompositions:

19 + 31538029 = 31538048
67 + 31537981 = 31538048
109 + 31537939 = 31538048
127 + 31537921 = 31538048
211 + 31537837 = 31538048
307 + 31537741 = 31538048
331 + 31537717 = 31538048
439 + 31537609 = 31538048

Showing the first eight; more decompositions exist.
