Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562150, here are decompositions:

13 + 31562137 = 31562150
31 + 31562119 = 31562150
43 + 31562107 = 31562150
97 + 31562053 = 31562150
127 + 31562023 = 31562150
157 + 31561993 = 31562150
181 + 31561969 = 31562150
211 + 31561939 = 31562150

Showing the first eight; more decompositions exist.
