Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527738, here are decompositions:

29 + 31527709 = 31527738
37 + 31527701 = 31527738
41 + 31527697 = 31527738
61 + 31527677 = 31527738
79 + 31527659 = 31527738
197 + 31527541 = 31527738
239 + 31527499 = 31527738
241 + 31527497 = 31527738

Showing the first eight; more decompositions exist.
