Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525532, here are decompositions:

43 + 31525489 = 31525532
271 + 31525261 = 31525532
331 + 31525201 = 31525532
349 + 31525183 = 31525532
541 + 31524991 = 31525532
739 + 31524793 = 31525532
769 + 31524763 = 31525532
811 + 31524721 = 31525532

Showing the first eight; more decompositions exist.
