Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542052, here are decompositions:

29 + 31542023 = 31542052
41 + 31542011 = 31542052
71 + 31541981 = 31542052
149 + 31541903 = 31542052
359 + 31541693 = 31542052
401 + 31541651 = 31542052
419 + 31541633 = 31542052
461 + 31541591 = 31542052

Showing the first eight; more decompositions exist.
