Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539862, here are decompositions:

5 + 31539857 = 31539862
23 + 31539839 = 31539862
41 + 31539821 = 31539862
149 + 31539713 = 31539862
191 + 31539671 = 31539862
269 + 31539593 = 31539862
293 + 31539569 = 31539862
449 + 31539413 = 31539862

Showing the first eight; more decompositions exist.
