Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477264, here are decompositions:

83 + 31477181 = 31477264
101 + 31477163 = 31477264
197 + 31477067 = 31477264
317 + 31476947 = 31477264
347 + 31476917 = 31477264
383 + 31476881 = 31477264
443 + 31476821 = 31477264
521 + 31476743 = 31477264

Showing the first eight; more decompositions exist.
