Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560074, here are decompositions:

97 + 31559977 = 31560074
163 + 31559911 = 31560074
223 + 31559851 = 31560074
241 + 31559833 = 31560074
397 + 31559677 = 31560074
421 + 31559653 = 31560074
433 + 31559641 = 31560074
607 + 31559467 = 31560074

Showing the first eight; more decompositions exist.
