Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588946, here are decompositions:

3 + 31588943 = 31588946
13 + 31588933 = 31588946
19 + 31588927 = 31588946
139 + 31588807 = 31588946
463 + 31588483 = 31588946
547 + 31588399 = 31588946
577 + 31588369 = 31588946
643 + 31588303 = 31588946

Showing the first eight; more decompositions exist.
