Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607012, here are decompositions:

61 + 31606951 = 31607012
109 + 31606903 = 31607012
271 + 31606741 = 31607012
331 + 31606681 = 31607012
433 + 31606579 = 31607012
601 + 31606411 = 31607012
631 + 31606381 = 31607012
643 + 31606369 = 31607012

Showing the first eight; more decompositions exist.
