Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542842, here are decompositions:

13 + 31542829 = 31542842
31 + 31542811 = 31542842
43 + 31542799 = 31542842
139 + 31542703 = 31542842
211 + 31542631 = 31542842
229 + 31542613 = 31542842
283 + 31542559 = 31542842
613 + 31542229 = 31542842

Showing the first eight; more decompositions exist.
