Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474182, here are decompositions:

11 + 31474171 = 31474182
41 + 31474141 = 31474182
53 + 31474129 = 31474182
71 + 31474111 = 31474182
109 + 31474073 = 31474182
139 + 31474043 = 31474182
149 + 31474033 = 31474182
191 + 31473991 = 31474182

Showing the first eight; more decompositions exist.
