Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547544, here are decompositions:

5 + 31547539 = 31547544
13 + 31547531 = 31547544
37 + 31547507 = 31547544
73 + 31547471 = 31547544
103 + 31547441 = 31547544
131 + 31547413 = 31547544
227 + 31547317 = 31547544
241 + 31547303 = 31547544

Showing the first eight; more decompositions exist.
