Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456098, here are decompositions:

5 + 31456093 = 31456098
19 + 31456079 = 31456098
31 + 31456067 = 31456098
137 + 31455961 = 31456098
139 + 31455959 = 31456098
151 + 31455947 = 31456098
197 + 31455901 = 31456098
229 + 31455869 = 31456098

Showing the first eight; more decompositions exist.
