Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542594, here are decompositions:

7 + 31542587 = 31542594
47 + 31542547 = 31542594
71 + 31542523 = 31542594
107 + 31542487 = 31542594
137 + 31542457 = 31542594
157 + 31542437 = 31542594
197 + 31542397 = 31542594
271 + 31542323 = 31542594

Showing the first eight; more decompositions exist.
