Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618098, here are decompositions:

37 + 31618061 = 31618098
41 + 31618057 = 31618098
97 + 31618001 = 31618098
101 + 31617997 = 31618098
131 + 31617967 = 31618098
137 + 31617961 = 31618098
139 + 31617959 = 31618098
157 + 31617941 = 31618098

Showing the first eight; more decompositions exist.
