Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483538, here are decompositions:

67 + 31483471 = 31483538
109 + 31483429 = 31483538
211 + 31483327 = 31483538
277 + 31483261 = 31483538
421 + 31483117 = 31483538
487 + 31483051 = 31483538
547 + 31482991 = 31483538
631 + 31482907 = 31483538

Showing the first eight; more decompositions exist.
