Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542248, here are decompositions:

19 + 31542229 = 31542248
181 + 31542067 = 31542248
211 + 31542037 = 31542248
271 + 31541977 = 31542248
277 + 31541971 = 31542248
349 + 31541899 = 31542248
379 + 31541869 = 31542248
421 + 31541827 = 31542248

Showing the first eight; more decompositions exist.
