Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467672, here are decompositions:

79 + 31467593 = 31467672
83 + 31467589 = 31467672
101 + 31467571 = 31467672
113 + 31467559 = 31467672
139 + 31467533 = 31467672
163 + 31467509 = 31467672
191 + 31467481 = 31467672
239 + 31467433 = 31467672

Showing the first eight; more decompositions exist.
