Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540850, here are decompositions:

13 + 31540837 = 31540850
37 + 31540813 = 31540850
67 + 31540783 = 31540850
127 + 31540723 = 31540850
151 + 31540699 = 31540850
157 + 31540693 = 31540850
181 + 31540669 = 31540850
193 + 31540657 = 31540850

Showing the first eight; more decompositions exist.
