Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482158, here are decompositions:

61 + 31482097 = 31482158
271 + 31481887 = 31482158
307 + 31481851 = 31482158
457 + 31481701 = 31482158
661 + 31481497 = 31482158
709 + 31481449 = 31482158
727 + 31481431 = 31482158
739 + 31481419 = 31482158

Showing the first eight; more decompositions exist.
