Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525450, here are decompositions:

3 + 31525447 = 31525450
29 + 31525421 = 31525450
53 + 31525397 = 31525450
71 + 31525379 = 31525450
83 + 31525367 = 31525450
107 + 31525343 = 31525450
167 + 31525283 = 31525450
239 + 31525211 = 31525450

Showing the first eight; more decompositions exist.
