Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495054, here are decompositions:

11 + 31495043 = 31495054
131 + 31494923 = 31495054
167 + 31494887 = 31495054
317 + 31494737 = 31495054
347 + 31494707 = 31495054
443 + 31494611 = 31495054
557 + 31494497 = 31495054
587 + 31494467 = 31495054

Showing the first eight; more decompositions exist.
