Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562118, here are decompositions:

11 + 31562107 = 31562118
19 + 31562099 = 31562118
61 + 31562057 = 31562118
101 + 31562017 = 31562118
109 + 31562009 = 31562118
149 + 31561969 = 31562118
151 + 31561967 = 31562118
179 + 31561939 = 31562118

Showing the first eight; more decompositions exist.
