Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600098, here are decompositions:

11 + 31600087 = 31600098
37 + 31600061 = 31600098
41 + 31600057 = 31600098
59 + 31600039 = 31600098
97 + 31600001 = 31600098
139 + 31599959 = 31600098
157 + 31599941 = 31600098
181 + 31599917 = 31600098

Showing the first eight; more decompositions exist.
