Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519098, here are decompositions:

7 + 31519091 = 31519098
29 + 31519069 = 31519098
31 + 31519067 = 31519098
41 + 31519057 = 31519098
109 + 31518989 = 31519098
137 + 31518961 = 31519098
199 + 31518899 = 31519098
229 + 31518869 = 31519098

Showing the first eight; more decompositions exist.
