Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461672, here are decompositions:

19 + 31461653 = 31461672
31 + 31461641 = 31461672
101 + 31461571 = 31461672
103 + 31461569 = 31461672
139 + 31461533 = 31461672
149 + 31461523 = 31461672
191 + 31461481 = 31461672
269 + 31461403 = 31461672

Showing the first eight; more decompositions exist.
