Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31988, here are decompositions:

7 + 31981 = 31988
31 + 31957 = 31988
97 + 31891 = 31988
139 + 31849 = 31988
331 + 31657 = 31988
421 + 31567 = 31988
457 + 31531 = 31988
499 + 31489 = 31988

Showing the first eight; more decompositions exist.
