Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456302, here are decompositions:

11 + 31456291 = 31456302
23 + 31456279 = 31456302
43 + 31456259 = 31456302
61 + 31456241 = 31456302
83 + 31456219 = 31456302
103 + 31456199 = 31456302
109 + 31456193 = 31456302
139 + 31456163 = 31456302

Showing the first eight; more decompositions exist.
