Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562564, here are decompositions:

13 + 31562551 = 31562564
97 + 31562467 = 31562564
283 + 31562281 = 31562564
307 + 31562257 = 31562564
457 + 31562107 = 31562564
541 + 31562023 = 31562564
547 + 31562017 = 31562564
571 + 31561993 = 31562564

Showing the first eight; more decompositions exist.
