Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731622, here are decompositions:

13 + 8731609 = 8731622
43 + 8731579 = 8731622
241 + 8731381 = 8731622
283 + 8731339 = 8731622
313 + 8731309 = 8731622
373 + 8731249 = 8731622
409 + 8731213 = 8731622
421 + 8731201 = 8731622

Showing the first eight; more decompositions exist.
