Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525670, here are decompositions:

13 + 31525657 = 31525670
19 + 31525651 = 31525670
61 + 31525609 = 31525670
67 + 31525603 = 31525670
103 + 31525567 = 31525670
181 + 31525489 = 31525670
193 + 31525477 = 31525670
223 + 31525447 = 31525670

Showing the first eight; more decompositions exist.
