Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562046, here are decompositions:

13 + 31562033 = 31562046
23 + 31562023 = 31562046
29 + 31562017 = 31562046
37 + 31562009 = 31562046
53 + 31561993 = 31562046
73 + 31561973 = 31562046
79 + 31561967 = 31562046
107 + 31561939 = 31562046

Showing the first eight; more decompositions exist.
