Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542494, here are decompositions:

7 + 31542487 = 31542494
37 + 31542457 = 31542494
97 + 31542397 = 31542494
103 + 31542391 = 31542494
331 + 31542163 = 31542494
457 + 31542037 = 31542494
463 + 31542031 = 31542494
523 + 31541971 = 31542494

Showing the first eight; more decompositions exist.
