Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523442, here are decompositions:

23 + 31523419 = 31523442
31 + 31523411 = 31523442
43 + 31523399 = 31523442
61 + 31523381 = 31523442
113 + 31523329 = 31523442
149 + 31523293 = 31523442
163 + 31523279 = 31523442
191 + 31523251 = 31523442

Showing the first eight; more decompositions exist.
