Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548482, here are decompositions:

139 + 31548343 = 31548482
151 + 31548331 = 31548482
181 + 31548301 = 31548482
349 + 31548133 = 31548482
373 + 31548109 = 31548482
379 + 31548103 = 31548482
523 + 31547959 = 31548482
631 + 31547851 = 31548482

Showing the first eight; more decompositions exist.
