Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477546, here are decompositions:

3 + 31477543 = 31477546
167 + 31477379 = 31477546
197 + 31477349 = 31477546
257 + 31477289 = 31477546
383 + 31477163 = 31477546
467 + 31477079 = 31477546
479 + 31477067 = 31477546
587 + 31476959 = 31477546

Showing the first eight; more decompositions exist.
