Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540174, here are decompositions:

11 + 31540163 = 31540174
167 + 31540007 = 31540174
311 + 31539863 = 31540174
317 + 31539857 = 31540174
353 + 31539821 = 31540174
461 + 31539713 = 31540174
467 + 31539707 = 31540174
503 + 31539671 = 31540174

Showing the first eight; more decompositions exist.
