Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105284, here are decompositions:

7 + 105277 = 105284
31 + 105253 = 105284
73 + 105211 = 105284
313 + 104971 = 105284
331 + 104953 = 105284
337 + 104947 = 105284
367 + 104917 = 105284
373 + 104911 = 105284

Showing the first eight; more decompositions exist.
