Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731382, here are decompositions:

13 + 8731369 = 8731382
19 + 8731363 = 8731382
43 + 8731339 = 8731382
61 + 8731321 = 8731382
73 + 8731309 = 8731382
151 + 8731231 = 8731382
181 + 8731201 = 8731382
229 + 8731153 = 8731382

Showing the first eight; more decompositions exist.
