Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618710, here are decompositions:

7 + 31618703 = 31618710
17 + 31618693 = 31618710
29 + 31618681 = 31618710
41 + 31618669 = 31618710
47 + 31618663 = 31618710
73 + 31618637 = 31618710
89 + 31618621 = 31618710
113 + 31618597 = 31618710

Showing the first eight; more decompositions exist.
