Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451696, here are decompositions:

79 + 31451617 = 31451696
109 + 31451587 = 31451696
193 + 31451503 = 31451696
313 + 31451383 = 31451696
349 + 31451347 = 31451696
373 + 31451323 = 31451696
457 + 31451239 = 31451696
487 + 31451209 = 31451696

Showing the first eight; more decompositions exist.
