Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455634, here are decompositions:

3 + 31455631 = 31455634
11 + 31455623 = 31455634
101 + 31455533 = 31455634
113 + 31455521 = 31455634
131 + 31455503 = 31455634
263 + 31455371 = 31455634
503 + 31455131 = 31455634
563 + 31455071 = 31455634

Showing the first eight; more decompositions exist.
