Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588954, here are decompositions:

3 + 31588951 = 31588954
11 + 31588943 = 31588954
107 + 31588847 = 31588954
281 + 31588673 = 31588954
311 + 31588643 = 31588954
347 + 31588607 = 31588954
431 + 31588523 = 31588954
461 + 31588493 = 31588954

Showing the first eight; more decompositions exist.
