Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468418, here are decompositions:

19 + 31468399 = 31468418
271 + 31468147 = 31468418
571 + 31467847 = 31468418
607 + 31467811 = 31468418
691 + 31467727 = 31468418
727 + 31467691 = 31468418
829 + 31467589 = 31468418
859 + 31467559 = 31468418

Showing the first eight; more decompositions exist.
