Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453232, here are decompositions:

61 + 31453171 = 31453232
73 + 31453159 = 31453232
193 + 31453039 = 31453232
211 + 31453021 = 31453232
331 + 31452901 = 31453232
373 + 31452859 = 31453232
439 + 31452793 = 31453232
463 + 31452769 = 31453232

Showing the first eight; more decompositions exist.
