Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456300, here are decompositions:

23 + 31456277 = 31456300
41 + 31456259 = 31456300
53 + 31456247 = 31456300
59 + 31456241 = 31456300
101 + 31456199 = 31456300
107 + 31456193 = 31456300
137 + 31456163 = 31456300
179 + 31456121 = 31456300

Showing the first eight; more decompositions exist.
