Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525546, here are decompositions:

47 + 31525499 = 31525546
149 + 31525397 = 31525546
167 + 31525379 = 31525546
179 + 31525367 = 31525546
257 + 31525289 = 31525546
263 + 31525283 = 31525546
317 + 31525229 = 31525546
383 + 31525163 = 31525546

Showing the first eight; more decompositions exist.
