Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499098, here are decompositions:

41 + 31499057 = 31499098
107 + 31498991 = 31499098
131 + 31498967 = 31499098
149 + 31498949 = 31499098
167 + 31498931 = 31499098
251 + 31498847 = 31499098
269 + 31498829 = 31499098
557 + 31498541 = 31499098

Showing the first eight; more decompositions exist.
