Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472426, here are decompositions:

67 + 31472359 = 31472426
277 + 31472149 = 31472426
283 + 31472143 = 31472426
373 + 31472053 = 31472426
397 + 31472029 = 31472426
487 + 31471939 = 31472426
577 + 31471849 = 31472426
787 + 31471639 = 31472426

Showing the first eight; more decompositions exist.
