Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591076, here are decompositions:

67 + 31591009 = 31591076
199 + 31590877 = 31591076
229 + 31590847 = 31591076
313 + 31590763 = 31591076
337 + 31590739 = 31591076
409 + 31590667 = 31591076
487 + 31590589 = 31591076
577 + 31590499 = 31591076

Showing the first eight; more decompositions exist.
