Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545492, here are decompositions:

5 + 31545487 = 31545492
23 + 31545469 = 31545492
53 + 31545439 = 31545492
101 + 31545391 = 31545492
113 + 31545379 = 31545492
149 + 31545343 = 31545492
163 + 31545329 = 31545492
193 + 31545299 = 31545492

Showing the first eight; more decompositions exist.
