Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588996, here are decompositions:

3 + 31588993 = 31588996
17 + 31588979 = 31588996
53 + 31588943 = 31588996
149 + 31588847 = 31588996
317 + 31588679 = 31588996
353 + 31588643 = 31588996
389 + 31588607 = 31588996
503 + 31588493 = 31588996

Showing the first eight; more decompositions exist.
