Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540234, here are decompositions:

17 + 31540217 = 31540234
23 + 31540211 = 31540234
53 + 31540181 = 31540234
71 + 31540163 = 31540234
227 + 31540007 = 31540234
263 + 31539971 = 31540234
521 + 31539713 = 31540234
563 + 31539671 = 31540234

Showing the first eight; more decompositions exist.
