Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475652, here are decompositions:

29 + 31475623 = 31475652
41 + 31475611 = 31475652
53 + 31475599 = 31475652
71 + 31475581 = 31475652
73 + 31475579 = 31475652
163 + 31475489 = 31475652
181 + 31475471 = 31475652
193 + 31475459 = 31475652

Showing the first eight; more decompositions exist.
