Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465970, here are decompositions:

79 + 31465891 = 31465970
139 + 31465831 = 31465970
181 + 31465789 = 31465970
223 + 31465747 = 31465970
229 + 31465741 = 31465970
307 + 31465663 = 31465970
409 + 31465561 = 31465970
607 + 31465363 = 31465970

Showing the first eight; more decompositions exist.
