Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453112, here are decompositions:

73 + 31453039 = 31453112
139 + 31452973 = 31453112
211 + 31452901 = 31453112
283 + 31452829 = 31453112
349 + 31452763 = 31453112
373 + 31452739 = 31453112
463 + 31452649 = 31453112
541 + 31452571 = 31453112

Showing the first eight; more decompositions exist.
