Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542506, here are decompositions:

19 + 31542487 = 31542506
67 + 31542439 = 31542506
109 + 31542397 = 31542506
277 + 31542229 = 31542506
439 + 31542067 = 31542506
607 + 31541899 = 31542506
613 + 31541893 = 31542506
769 + 31541737 = 31542506

Showing the first eight; more decompositions exist.
