Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479054, here are decompositions:

23 + 31479031 = 31479054
37 + 31479017 = 31479054
53 + 31479001 = 31479054
71 + 31478983 = 31479054
97 + 31478957 = 31479054
223 + 31478831 = 31479054
317 + 31478737 = 31479054
353 + 31478701 = 31479054

Showing the first eight; more decompositions exist.
