Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477426, here are decompositions:

3 + 31477423 = 31477426
47 + 31477379 = 31477426
137 + 31477289 = 31477426
263 + 31477163 = 31477426
347 + 31477079 = 31477426
359 + 31477067 = 31477426
467 + 31476959 = 31477426
479 + 31476947 = 31477426

Showing the first eight; more decompositions exist.
