Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467970, here are decompositions:

3 + 31467967 = 31467970
59 + 31467911 = 31467970
71 + 31467899 = 31467970
251 + 31467719 = 31467970
293 + 31467677 = 31467970
383 + 31467587 = 31467970
419 + 31467551 = 31467970
431 + 31467539 = 31467970

Showing the first eight; more decompositions exist.
