Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538862, here are decompositions:

73 + 31538789 = 31538862
83 + 31538779 = 31538862
109 + 31538753 = 31538862
149 + 31538713 = 31538862
151 + 31538711 = 31538862
191 + 31538671 = 31538862
233 + 31538629 = 31538862
239 + 31538623 = 31538862

Showing the first eight; more decompositions exist.
