Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618954, here are decompositions:

5 + 31618949 = 31618954
11 + 31618943 = 31618954
53 + 31618901 = 31618954
71 + 31618883 = 31618954
83 + 31618871 = 31618954
131 + 31618823 = 31618954
173 + 31618781 = 31618954
251 + 31618703 = 31618954

Showing the first eight; more decompositions exist.
