Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537054, here are decompositions:

5 + 31537049 = 31537054
11 + 31537043 = 31537054
53 + 31537001 = 31537054
71 + 31536983 = 31537054
137 + 31536917 = 31537054
191 + 31536863 = 31537054
233 + 31536821 = 31537054
281 + 31536773 = 31537054

Showing the first eight; more decompositions exist.
