Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618622, here are decompositions:

43 + 31618579 = 31618622
73 + 31618549 = 31618622
103 + 31618519 = 31618622
181 + 31618441 = 31618622
199 + 31618423 = 31618622
433 + 31618189 = 31618622
523 + 31618099 = 31618622
619 + 31618003 = 31618622

Showing the first eight; more decompositions exist.
