Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473852, here are decompositions:

5 + 31473847 = 31473852
13 + 31473839 = 31473852
41 + 31473811 = 31473852
43 + 31473809 = 31473852
71 + 31473781 = 31473852
73 + 31473779 = 31473852
149 + 31473703 = 31473852
269 + 31473583 = 31473852

Showing the first eight; more decompositions exist.
