Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477684, here are decompositions:

101 + 31477583 = 31477684
107 + 31477577 = 31477684
113 + 31477571 = 31477684
131 + 31477553 = 31477684
257 + 31477427 = 31477684
383 + 31477301 = 31477684
503 + 31477181 = 31477684
521 + 31477163 = 31477684

Showing the first eight; more decompositions exist.
