Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547030, here are decompositions:

43 + 31546987 = 31547030
61 + 31546969 = 31547030
139 + 31546891 = 31547030
199 + 31546831 = 31547030
223 + 31546807 = 31547030
241 + 31546789 = 31547030
271 + 31546759 = 31547030
313 + 31546717 = 31547030

Showing the first eight; more decompositions exist.
