Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485482, here are decompositions:

103 + 31485379 = 31485482
163 + 31485319 = 31485482
181 + 31485301 = 31485482
199 + 31485283 = 31485482
433 + 31485049 = 31485482
463 + 31485019 = 31485482
541 + 31484941 = 31485482
571 + 31484911 = 31485482

Showing the first eight; more decompositions exist.
