Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562066, here are decompositions:

13 + 31562053 = 31562066
43 + 31562023 = 31562066
73 + 31561993 = 31562066
97 + 31561969 = 31562066
127 + 31561939 = 31562066
139 + 31561927 = 31562066
163 + 31561903 = 31562066
313 + 31561753 = 31562066

Showing the first eight; more decompositions exist.
