Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538824, here are decompositions:

17 + 31538807 = 31538824
71 + 31538753 = 31538824
113 + 31538711 = 31538824
131 + 31538693 = 31538824
263 + 31538561 = 31538824
347 + 31538477 = 31538824
491 + 31538333 = 31538824
563 + 31538261 = 31538824

Showing the first eight; more decompositions exist.
