Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540024, here are decompositions:

11 + 31540013 = 31540024
17 + 31540007 = 31540024
53 + 31539971 = 31540024
167 + 31539857 = 31540024
311 + 31539713 = 31540024
317 + 31539707 = 31540024
353 + 31539671 = 31540024
431 + 31539593 = 31540024

Showing the first eight; more decompositions exist.
