Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562030, here are decompositions:

7 + 31562023 = 31562030
13 + 31562017 = 31562030
37 + 31561993 = 31562030
61 + 31561969 = 31562030
103 + 31561927 = 31562030
127 + 31561903 = 31562030
223 + 31561807 = 31562030
229 + 31561801 = 31562030

Showing the first eight; more decompositions exist.
