Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474152, here are decompositions:

11 + 31474141 = 31474152
23 + 31474129 = 31474152
41 + 31474111 = 31474152
79 + 31474073 = 31474152
109 + 31474043 = 31474152
181 + 31473971 = 31474152
251 + 31473901 = 31474152
313 + 31473839 = 31474152

Showing the first eight; more decompositions exist.
