Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473912, here are decompositions:

5 + 31473907 = 31473912
11 + 31473901 = 31473912
73 + 31473839 = 31473912
101 + 31473811 = 31473912
103 + 31473809 = 31473912
131 + 31473781 = 31473912
179 + 31473733 = 31473912
313 + 31473599 = 31473912

Showing the first eight; more decompositions exist.
