Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535718, here are decompositions:

37 + 31535681 = 31535718
47 + 31535671 = 31535718
61 + 31535657 = 31535718
79 + 31535639 = 31535718
127 + 31535591 = 31535718
167 + 31535551 = 31535718
251 + 31535467 = 31535718
307 + 31535411 = 31535718

Showing the first eight; more decompositions exist.
