Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562666, here are decompositions:

43 + 31562623 = 31562666
73 + 31562593 = 31562666
199 + 31562467 = 31562666
277 + 31562389 = 31562666
337 + 31562329 = 31562666
367 + 31562299 = 31562666
409 + 31562257 = 31562666
547 + 31562119 = 31562666

Showing the first eight; more decompositions exist.
