Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618602, here are decompositions:

5 + 31618597 = 31618602
23 + 31618579 = 31618602
53 + 31618549 = 31618602
83 + 31618519 = 31618602
139 + 31618463 = 31618602
179 + 31618423 = 31618602
193 + 31618409 = 31618602
199 + 31618403 = 31618602

Showing the first eight; more decompositions exist.
