Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461606, here are decompositions:

37 + 31461569 = 31461606
53 + 31461553 = 31461606
73 + 31461533 = 31461606
83 + 31461523 = 31461606
89 + 31461517 = 31461606
149 + 31461457 = 31461606
179 + 31461427 = 31461606
193 + 31461413 = 31461606

Showing the first eight; more decompositions exist.
