Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455852, here are decompositions:

11 + 31455841 = 31455852
23 + 31455829 = 31455852
31 + 31455821 = 31455852
101 + 31455751 = 31455852
139 + 31455713 = 31455852
149 + 31455703 = 31455852
151 + 31455701 = 31455852
229 + 31455623 = 31455852

Showing the first eight; more decompositions exist.
