Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618498, here are decompositions:

89 + 31618409 = 31618498
137 + 31618361 = 31618498
179 + 31618319 = 31618498
311 + 31618187 = 31618498
449 + 31618049 = 31618498
557 + 31617941 = 31618498
599 + 31617899 = 31618498
701 + 31617797 = 31618498

Showing the first eight; more decompositions exist.
