Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525672, here are decompositions:

23 + 31525649 = 31525672
71 + 31525601 = 31525672
83 + 31525589 = 31525672
173 + 31525499 = 31525672
251 + 31525421 = 31525672
293 + 31525379 = 31525672
383 + 31525289 = 31525672
389 + 31525283 = 31525672

Showing the first eight; more decompositions exist.
