Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542848, here are decompositions:

19 + 31542829 = 31542848
37 + 31542811 = 31542848
61 + 31542787 = 31542848
151 + 31542697 = 31542848
409 + 31542439 = 31542848
457 + 31542391 = 31542848
619 + 31542229 = 31542848
811 + 31542037 = 31542848

Showing the first eight; more decompositions exist.
