Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542094, here are decompositions:

11 + 31542083 = 31542094
71 + 31542023 = 31542094
83 + 31542011 = 31542094
113 + 31541981 = 31542094
191 + 31541903 = 31542094
401 + 31541693 = 31542094
443 + 31541651 = 31542094
461 + 31541633 = 31542094

Showing the first eight; more decompositions exist.
