Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532546, here are decompositions:

7 + 31532539 = 31532546
109 + 31532437 = 31532546
193 + 31532353 = 31532546
223 + 31532323 = 31532546
277 + 31532269 = 31532546
337 + 31532209 = 31532546
379 + 31532167 = 31532546
433 + 31532113 = 31532546

Showing the first eight; more decompositions exist.
