Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534098, here are decompositions:

19 + 31534079 = 31534098
31 + 31534067 = 31534098
41 + 31534057 = 31534098
47 + 31534051 = 31534098
131 + 31533967 = 31534098
139 + 31533959 = 31534098
149 + 31533949 = 31534098
179 + 31533919 = 31534098

Showing the first eight; more decompositions exist.
