Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492648, here are decompositions:

71 + 31492577 = 31492648
107 + 31492541 = 31492648
227 + 31492421 = 31492648
311 + 31492337 = 31492648
389 + 31492259 = 31492648
491 + 31492157 = 31492648
557 + 31492091 = 31492648
569 + 31492079 = 31492648

Showing the first eight; more decompositions exist.
