Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453606, here are decompositions:

29 + 31453577 = 31453606
83 + 31453523 = 31453606
179 + 31453427 = 31453606
449 + 31453157 = 31453606
857 + 31452749 = 31453606
887 + 31452719 = 31453606
929 + 31452677 = 31453606
983 + 31452623 = 31453606

Showing the first eight; more decompositions exist.
