Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591052, here are decompositions:

43 + 31591009 = 31591052
61 + 31590991 = 31591052
109 + 31590943 = 31591052
211 + 31590841 = 31591052
313 + 31590739 = 31591052
421 + 31590631 = 31591052
463 + 31590589 = 31591052
601 + 31590451 = 31591052

Showing the first eight; more decompositions exist.
