Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540408, here are decompositions:

167 + 31540241 = 31540408
191 + 31540217 = 31540408
197 + 31540211 = 31540408
227 + 31540181 = 31540408
401 + 31540007 = 31540408
569 + 31539839 = 31540408
587 + 31539821 = 31540408
701 + 31539707 = 31540408

Showing the first eight; more decompositions exist.
