Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525676, here are decompositions:

19 + 31525657 = 31525676
67 + 31525609 = 31525676
73 + 31525603 = 31525676
109 + 31525567 = 31525676
139 + 31525537 = 31525676
199 + 31525477 = 31525676
229 + 31525447 = 31525676
397 + 31525279 = 31525676

Showing the first eight; more decompositions exist.
