Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560044, here are decompositions:

67 + 31559977 = 31560044
193 + 31559851 = 31560044
211 + 31559833 = 31560044
223 + 31559821 = 31560044
367 + 31559677 = 31560044
421 + 31559623 = 31560044
577 + 31559467 = 31560044
601 + 31559443 = 31560044

Showing the first eight; more decompositions exist.
