Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529486, here are decompositions:

7 + 31529479 = 31529486
73 + 31529413 = 31529486
127 + 31529359 = 31529486
139 + 31529347 = 31529486
229 + 31529257 = 31529486
337 + 31529149 = 31529486
379 + 31529107 = 31529486
397 + 31529089 = 31529486

Showing the first eight; more decompositions exist.
