Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516254, here are decompositions:

13 + 31516241 = 31516254
17 + 31516237 = 31516254
53 + 31516201 = 31516254
71 + 31516183 = 31516254
97 + 31516157 = 31516254
101 + 31516153 = 31516254
131 + 31516123 = 31516254
151 + 31516103 = 31516254

Showing the first eight; more decompositions exist.
