Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542588, here are decompositions:

29 + 31542559 = 31542588
41 + 31542547 = 31542588
79 + 31542509 = 31542588
101 + 31542487 = 31542588
109 + 31542479 = 31542588
131 + 31542457 = 31542588
149 + 31542439 = 31542588
151 + 31542437 = 31542588

Showing the first eight; more decompositions exist.
