Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457450, here are decompositions:

67 + 31457383 = 31457450
103 + 31457347 = 31457450
109 + 31457341 = 31457450
139 + 31457311 = 31457450
163 + 31457287 = 31457450
181 + 31457269 = 31457450
223 + 31457227 = 31457450
331 + 31457119 = 31457450

Showing the first eight; more decompositions exist.
