Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461522, here are decompositions:

5 + 31461517 = 31461522
41 + 31461481 = 31461522
109 + 31461413 = 31461522
173 + 31461349 = 31461522
179 + 31461343 = 31461522
181 + 31461341 = 31461522
229 + 31461293 = 31461522
241 + 31461281 = 31461522

Showing the first eight; more decompositions exist.
