Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456184, here are decompositions:

61 + 31456123 = 31456184
163 + 31456021 = 31456184
181 + 31456003 = 31456184
223 + 31455961 = 31456184
283 + 31455901 = 31456184
307 + 31455877 = 31456184
433 + 31455751 = 31456184
457 + 31455727 = 31456184

Showing the first eight; more decompositions exist.
