Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681382, here are decompositions:

5 + 8681377 = 8681382
13 + 8681369 = 8681382
19 + 8681363 = 8681382
23 + 8681359 = 8681382
41 + 8681341 = 8681382
71 + 8681311 = 8681382
131 + 8681251 = 8681382
139 + 8681243 = 8681382

Showing the first eight; more decompositions exist.
