Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588376, here are decompositions:

7 + 31588369 = 31588376
19 + 31588357 = 31588376
73 + 31588303 = 31588376
109 + 31588267 = 31588376
373 + 31588003 = 31588376
397 + 31587979 = 31588376
433 + 31587943 = 31588376
499 + 31587877 = 31588376

Showing the first eight; more decompositions exist.
