Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473482, here are decompositions:

3 + 31473479 = 31473482
151 + 31473331 = 31473482
199 + 31473283 = 31473482
241 + 31473241 = 31473482
331 + 31473151 = 31473482
373 + 31473109 = 31473482
421 + 31473061 = 31473482
499 + 31472983 = 31473482

Showing the first eight; more decompositions exist.
