Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525094, here are decompositions:

67 + 31525027 = 31525094
103 + 31524991 = 31525094
127 + 31524967 = 31525094
157 + 31524937 = 31525094
331 + 31524763 = 31525094
373 + 31524721 = 31525094
421 + 31524673 = 31525094
487 + 31524607 = 31525094

Showing the first eight; more decompositions exist.
