Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627098, here are decompositions:

7 + 31627091 = 31627098
29 + 31627069 = 31627098
47 + 31627051 = 31627098
71 + 31627027 = 31627098
131 + 31626967 = 31627098
199 + 31626899 = 31627098
229 + 31626869 = 31627098
241 + 31626857 = 31627098

Showing the first eight; more decompositions exist.
