Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473654, here are decompositions:

61 + 31473593 = 31473654
71 + 31473583 = 31473654
73 + 31473581 = 31473654
131 + 31473523 = 31473654
167 + 31473487 = 31473654
197 + 31473457 = 31473654
241 + 31473413 = 31473654
257 + 31473397 = 31473654

Showing the first eight; more decompositions exist.
