Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543492, here are decompositions:

3 + 31543489 = 31543492
11 + 31543481 = 31543492
41 + 31543451 = 31543492
131 + 31543361 = 31543492
191 + 31543301 = 31543492
269 + 31543223 = 31543492
311 + 31543181 = 31543492
359 + 31543133 = 31543492

Showing the first eight; more decompositions exist.
