Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477174, here are decompositions:

11 + 31477163 = 31477174
107 + 31477067 = 31477174
227 + 31476947 = 31477174
257 + 31476917 = 31477174
293 + 31476881 = 31477174
353 + 31476821 = 31477174
431 + 31476743 = 31477174
563 + 31476611 = 31477174

Showing the first eight; more decompositions exist.
