Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538946, here are decompositions:

59 + 31538887 = 31538946
139 + 31538807 = 31538946
157 + 31538789 = 31538946
167 + 31538779 = 31538946
193 + 31538753 = 31538946
227 + 31538719 = 31538946
233 + 31538713 = 31538946
293 + 31538653 = 31538946

Showing the first eight; more decompositions exist.
