Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540196, here are decompositions:

7 + 31540189 = 31540196
73 + 31540123 = 31540196
97 + 31540099 = 31540196
229 + 31539967 = 31540196
307 + 31539889 = 31540196
379 + 31539817 = 31540196
433 + 31539763 = 31540196
439 + 31539757 = 31540196

Showing the first eight; more decompositions exist.
