Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542548, here are decompositions:

61 + 31542487 = 31542548
109 + 31542439 = 31542548
151 + 31542397 = 31542548
157 + 31542391 = 31542548
547 + 31542001 = 31542548
571 + 31541977 = 31542548
577 + 31541971 = 31542548
691 + 31541857 = 31542548

Showing the first eight; more decompositions exist.
