Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542410, here are decompositions:

13 + 31542397 = 31542410
19 + 31542391 = 31542410
37 + 31542373 = 31542410
181 + 31542229 = 31542410
307 + 31542103 = 31542410
373 + 31542037 = 31542410
379 + 31542031 = 31542410
397 + 31542013 = 31542410

Showing the first eight; more decompositions exist.
