Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562894, here are decompositions:

67 + 31562827 = 31562894
127 + 31562767 = 31562894
157 + 31562737 = 31562894
211 + 31562683 = 31562894
271 + 31562623 = 31562894
277 + 31562617 = 31562894
283 + 31562611 = 31562894
463 + 31562431 = 31562894

Showing the first eight; more decompositions exist.
