Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480054, here are decompositions:

5 + 31480049 = 31480054
107 + 31479947 = 31480054
173 + 31479881 = 31480054
197 + 31479857 = 31480054
233 + 31479821 = 31480054
251 + 31479803 = 31480054
311 + 31479743 = 31480054
317 + 31479737 = 31480054

Showing the first eight; more decompositions exist.
