Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525526, here are decompositions:

37 + 31525489 = 31525526
79 + 31525447 = 31525526
283 + 31525243 = 31525526
313 + 31525213 = 31525526
349 + 31525177 = 31525526
499 + 31525027 = 31525526
733 + 31524793 = 31525526
853 + 31524673 = 31525526

Showing the first eight; more decompositions exist.
