Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535862, here are decompositions:

31 + 31535831 = 31535862
41 + 31535821 = 31535862
53 + 31535809 = 31535862
109 + 31535753 = 31535862
181 + 31535681 = 31535862
191 + 31535671 = 31535862
223 + 31535639 = 31535862
229 + 31535633 = 31535862

Showing the first eight; more decompositions exist.
