Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538092, here are decompositions:

29 + 31538063 = 31538092
59 + 31538033 = 31538092
233 + 31537859 = 31538092
269 + 31537823 = 31538092
401 + 31537691 = 31538092
461 + 31537631 = 31538092
659 + 31537433 = 31538092
683 + 31537409 = 31538092

Showing the first eight; more decompositions exist.
