Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489482, here are decompositions:

19 + 31489463 = 31489482
71 + 31489411 = 31489482
83 + 31489399 = 31489482
223 + 31489259 = 31489482
239 + 31489243 = 31489482
313 + 31489169 = 31489482
419 + 31489063 = 31489482
439 + 31489043 = 31489482

Showing the first eight; more decompositions exist.
