Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538426, here are decompositions:

19 + 31538407 = 31538426
97 + 31538329 = 31538426
223 + 31538203 = 31538426
313 + 31538113 = 31538426
373 + 31538053 = 31538426
379 + 31538047 = 31538426
397 + 31538029 = 31538426
487 + 31537939 = 31538426

Showing the first eight; more decompositions exist.
