Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480522, here are decompositions:

89 + 31480433 = 31480522
131 + 31480391 = 31480522
149 + 31480373 = 31480522
173 + 31480349 = 31480522
233 + 31480289 = 31480522
263 + 31480259 = 31480522
419 + 31480103 = 31480522
431 + 31480091 = 31480522

Showing the first eight; more decompositions exist.
