Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562306, here are decompositions:

7 + 31562299 = 31562306
43 + 31562263 = 31562306
199 + 31562107 = 31562306
283 + 31562023 = 31562306
313 + 31561993 = 31562306
337 + 31561969 = 31562306
367 + 31561939 = 31562306
379 + 31561927 = 31562306

Showing the first eight; more decompositions exist.
