Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473472, here are decompositions:

59 + 31473413 = 31473472
113 + 31473359 = 31473472
263 + 31473209 = 31473472
269 + 31473203 = 31473472
281 + 31473191 = 31473472
311 + 31473161 = 31473472
389 + 31473083 = 31473472
431 + 31473041 = 31473472

Showing the first eight; more decompositions exist.
