Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562002, here are decompositions:

29 + 31561973 = 31562002
83 + 31561919 = 31562002
179 + 31561823 = 31562002
191 + 31561811 = 31562002
359 + 31561643 = 31562002
503 + 31561499 = 31562002
569 + 31561433 = 31562002
599 + 31561403 = 31562002

Showing the first eight; more decompositions exist.
