Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562998, here are decompositions:

11 + 31562987 = 31562998
17 + 31562981 = 31562998
149 + 31562849 = 31562998
197 + 31562801 = 31562998
431 + 31562567 = 31562998
479 + 31562519 = 31562998
557 + 31562441 = 31562998
569 + 31562429 = 31562998

Showing the first eight; more decompositions exist.
