Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474052, here are decompositions:

19 + 31474033 = 31474052
61 + 31473991 = 31474052
151 + 31473901 = 31474052
241 + 31473811 = 31474052
271 + 31473781 = 31474052
349 + 31473703 = 31474052
523 + 31473529 = 31474052
739 + 31473313 = 31474052

Showing the first eight; more decompositions exist.
