Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562338, here are decompositions:

47 + 31562291 = 31562338
107 + 31562231 = 31562338
239 + 31562099 = 31562338
281 + 31562057 = 31562338
419 + 31561919 = 31562338
491 + 31561847 = 31562338
557 + 31561781 = 31562338
641 + 31561697 = 31562338

Showing the first eight; more decompositions exist.
