Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591496, here are decompositions:

3 + 31591493 = 31591496
19 + 31591477 = 31591496
43 + 31591453 = 31591496
337 + 31591159 = 31591496
397 + 31591099 = 31591496
487 + 31591009 = 31591496
619 + 31590877 = 31591496
733 + 31590763 = 31591496

Showing the first eight; more decompositions exist.
