Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607192, here are decompositions:

229 + 31606963 = 31607192
241 + 31606951 = 31607192
313 + 31606879 = 31607192
439 + 31606753 = 31607192
541 + 31606651 = 31607192
613 + 31606579 = 31607192
769 + 31606423 = 31607192
811 + 31606381 = 31607192

Showing the first eight; more decompositions exist.
