Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446522, here are decompositions:

31 + 31446491 = 31446522
61 + 31446461 = 31446522
83 + 31446439 = 31446522
181 + 31446341 = 31446522
193 + 31446329 = 31446522
199 + 31446323 = 31446522
269 + 31446253 = 31446522
271 + 31446251 = 31446522

Showing the first eight; more decompositions exist.
