Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534054, here are decompositions:

3 + 31534051 = 31534054
131 + 31533923 = 31534054
263 + 31533791 = 31534054
281 + 31533773 = 31534054
347 + 31533707 = 31534054
443 + 31533611 = 31534054
467 + 31533587 = 31534054
491 + 31533563 = 31534054

Showing the first eight; more decompositions exist.
