Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618606, here are decompositions:

59 + 31618547 = 31618606
197 + 31618409 = 31618606
317 + 31618289 = 31618606
419 + 31618187 = 31618606
443 + 31618163 = 31618606
479 + 31618127 = 31618606
557 + 31618049 = 31618606
563 + 31618043 = 31618606

Showing the first eight; more decompositions exist.
