Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547186, here are decompositions:

43 + 31547143 = 31547186
109 + 31547077 = 31547186
199 + 31546987 = 31547186
277 + 31546909 = 31547186
373 + 31546813 = 31547186
379 + 31546807 = 31547186
397 + 31546789 = 31547186
523 + 31546663 = 31547186

Showing the first eight; more decompositions exist.
