Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562270, here are decompositions:

7 + 31562263 = 31562270
13 + 31562257 = 31562270
151 + 31562119 = 31562270
163 + 31562107 = 31562270
277 + 31561993 = 31562270
331 + 31561939 = 31562270
367 + 31561903 = 31562270
463 + 31561807 = 31562270

Showing the first eight; more decompositions exist.
