Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618010, here are decompositions:

7 + 31618003 = 31618010
13 + 31617997 = 31618010
43 + 31617967 = 31618010
139 + 31617871 = 31618010
157 + 31617853 = 31618010
199 + 31617811 = 31618010
313 + 31617697 = 31618010
331 + 31617679 = 31618010

Showing the first eight; more decompositions exist.
