Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562354, here are decompositions:

7 + 31562347 = 31562354
73 + 31562281 = 31562354
97 + 31562257 = 31562354
331 + 31562023 = 31562354
337 + 31562017 = 31562354
547 + 31561807 = 31562354
601 + 31561753 = 31562354
631 + 31561723 = 31562354

Showing the first eight; more decompositions exist.
