Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534378, here are decompositions:

107 + 31534271 = 31534378
131 + 31534247 = 31534378
137 + 31534241 = 31534378
179 + 31534199 = 31534378
191 + 31534187 = 31534378
257 + 31534121 = 31534378
311 + 31534067 = 31534378
419 + 31533959 = 31534378

Showing the first eight; more decompositions exist.
