Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625526, here are decompositions:

17 + 31625509 = 31625526
19 + 31625507 = 31625526
59 + 31625467 = 31625526
73 + 31625453 = 31625526
223 + 31625303 = 31625526
263 + 31625263 = 31625526
347 + 31625179 = 31625526
379 + 31625147 = 31625526

Showing the first eight; more decompositions exist.
