Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562412, here are decompositions:

23 + 31562389 = 31562412
83 + 31562329 = 31562412
113 + 31562299 = 31562412
131 + 31562281 = 31562412
139 + 31562273 = 31562412
149 + 31562263 = 31562412
151 + 31562261 = 31562412
181 + 31562231 = 31562412

Showing the first eight; more decompositions exist.
