Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538932, here are decompositions:

179 + 31538753 = 31538932
239 + 31538693 = 31538932
353 + 31538579 = 31538932
443 + 31538489 = 31538932
521 + 31538411 = 31538932
599 + 31538333 = 31538932
1061 + 31537871 = 31538932
1109 + 31537823 = 31538932

Showing the first eight; more decompositions exist.
