Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454044, here are decompositions:

47 + 31453997 = 31454044
53 + 31453991 = 31454044
101 + 31453943 = 31454044
113 + 31453931 = 31454044
311 + 31453733 = 31454044
317 + 31453727 = 31454044
467 + 31453577 = 31454044
521 + 31453523 = 31454044

Showing the first eight; more decompositions exist.
