Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540030, here are decompositions:

17 + 31540013 = 31540030
23 + 31540007 = 31540030
59 + 31539971 = 31540030
167 + 31539863 = 31540030
173 + 31539857 = 31540030
191 + 31539839 = 31540030
293 + 31539737 = 31540030
317 + 31539713 = 31540030

Showing the first eight; more decompositions exist.
