Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477276, here are decompositions:

113 + 31477163 = 31477276
197 + 31477079 = 31477276
317 + 31476959 = 31477276
359 + 31476917 = 31477276
653 + 31476623 = 31477276
683 + 31476593 = 31477276
827 + 31476449 = 31477276
839 + 31476437 = 31477276

Showing the first eight; more decompositions exist.
