Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538752, here are decompositions:

23 + 31538729 = 31538752
41 + 31538711 = 31538752
59 + 31538693 = 31538752
173 + 31538579 = 31538752
191 + 31538561 = 31538752
263 + 31538489 = 31538752
419 + 31538333 = 31538752
491 + 31538261 = 31538752

Showing the first eight; more decompositions exist.
