Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527862, here are decompositions:

173 + 31527689 = 31527862
293 + 31527569 = 31527862
449 + 31527413 = 31527862
719 + 31527143 = 31527862
941 + 31526921 = 31527862
983 + 31526879 = 31527862
1091 + 31526771 = 31527862
1109 + 31526753 = 31527862

Showing the first eight; more decompositions exist.
