Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473672, here are decompositions:

73 + 31473599 = 31473672
79 + 31473593 = 31473672
89 + 31473583 = 31473672
149 + 31473523 = 31473672
193 + 31473479 = 31473672
313 + 31473359 = 31473672
359 + 31473313 = 31473672
389 + 31473283 = 31473672

Showing the first eight; more decompositions exist.
