Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464870, here are decompositions:

43 + 31464827 = 31464870
61 + 31464809 = 31464870
83 + 31464787 = 31464870
89 + 31464781 = 31464870
113 + 31464757 = 31464870
139 + 31464731 = 31464870
251 + 31464619 = 31464870
293 + 31464577 = 31464870

Showing the first eight; more decompositions exist.
