Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473582, here are decompositions:

53 + 31473529 = 31473582
59 + 31473523 = 31473582
103 + 31473479 = 31473582
223 + 31473359 = 31473582
251 + 31473331 = 31473582
269 + 31473313 = 31473582
331 + 31473251 = 31473582
373 + 31473209 = 31473582

Showing the first eight; more decompositions exist.
