Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534030, here are decompositions:

71 + 31533959 = 31534030
107 + 31533923 = 31534030
191 + 31533839 = 31534030
197 + 31533833 = 31534030
239 + 31533791 = 31534030
257 + 31533773 = 31534030
389 + 31533641 = 31534030
419 + 31533611 = 31534030

Showing the first eight; more decompositions exist.
