Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534718, here are decompositions:

67 + 31534651 = 31534718
157 + 31534561 = 31534718
277 + 31534441 = 31534718
307 + 31534411 = 31534718
349 + 31534369 = 31534718
421 + 31534297 = 31534718
487 + 31534231 = 31534718
577 + 31534141 = 31534718

Showing the first eight; more decompositions exist.
