Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485522, here are decompositions:

73 + 31485449 = 31485522
139 + 31485383 = 31485522
163 + 31485359 = 31485522
181 + 31485341 = 31485522
239 + 31485283 = 31485522
331 + 31485191 = 31485522
401 + 31485121 = 31485522
421 + 31485101 = 31485522

Showing the first eight; more decompositions exist.
