Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542892, here are decompositions:

11 + 31542881 = 31542892
83 + 31542809 = 31542892
233 + 31542659 = 31542892
383 + 31542509 = 31542892
569 + 31542323 = 31542892
659 + 31542233 = 31542892
743 + 31542149 = 31542892
809 + 31542083 = 31542892

Showing the first eight; more decompositions exist.
