Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468112, here are decompositions:

163 + 31467949 = 31468112
283 + 31467829 = 31468112
349 + 31467763 = 31468112
421 + 31467691 = 31468112
523 + 31467589 = 31468112
541 + 31467571 = 31468112
631 + 31467481 = 31468112
811 + 31467301 = 31468112

Showing the first eight; more decompositions exist.
