Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540108, here are decompositions:

101 + 31540007 = 31540108
137 + 31539971 = 31540108
251 + 31539857 = 31540108
269 + 31539839 = 31540108
401 + 31539707 = 31540108
449 + 31539659 = 31540108
521 + 31539587 = 31540108
641 + 31539467 = 31540108

Showing the first eight; more decompositions exist.
