Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588974, here are decompositions:

17 + 31588957 = 31588974
23 + 31588951 = 31588974
31 + 31588943 = 31588974
41 + 31588933 = 31588974
47 + 31588927 = 31588974
127 + 31588847 = 31588974
167 + 31588807 = 31588974
281 + 31588693 = 31588974

Showing the first eight; more decompositions exist.
