Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480098, here are decompositions:

7 + 31480091 = 31480098
19 + 31480079 = 31480098
37 + 31480061 = 31480098
79 + 31480019 = 31480098
137 + 31479961 = 31480098
149 + 31479949 = 31480098
151 + 31479947 = 31480098
241 + 31479857 = 31480098

Showing the first eight; more decompositions exist.
