Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473652, here are decompositions:

53 + 31473599 = 31473652
59 + 31473593 = 31473652
71 + 31473581 = 31473652
173 + 31473479 = 31473652
239 + 31473413 = 31473652
293 + 31473359 = 31473652
389 + 31473263 = 31473652
401 + 31473251 = 31473652

Showing the first eight; more decompositions exist.
