Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562966, here are decompositions:

7 + 31562959 = 31562966
139 + 31562827 = 31562966
199 + 31562767 = 31562966
229 + 31562737 = 31562966
283 + 31562683 = 31562966
349 + 31562617 = 31562966
373 + 31562593 = 31562966
499 + 31562467 = 31562966

Showing the first eight; more decompositions exist.
