Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747382, here are decompositions:

53 + 8747329 = 8747382
109 + 8747273 = 8747382
131 + 8747251 = 8747382
139 + 8747243 = 8747382
191 + 8747191 = 8747382
211 + 8747171 = 8747382
223 + 8747159 = 8747382
263 + 8747119 = 8747382

Showing the first eight; more decompositions exist.
