Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529186, here are decompositions:

19 + 31529167 = 31529186
37 + 31529149 = 31529186
79 + 31529107 = 31529186
97 + 31529089 = 31529186
193 + 31528993 = 31529186
277 + 31528909 = 31529186
373 + 31528813 = 31529186
379 + 31528807 = 31529186

Showing the first eight; more decompositions exist.
