Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709782, here are decompositions:

31 + 8709751 = 8709782
61 + 8709721 = 8709782
229 + 8709553 = 8709782
313 + 8709469 = 8709782
409 + 8709373 = 8709782
421 + 8709361 = 8709782
643 + 8709139 = 8709782
661 + 8709121 = 8709782

Showing the first eight; more decompositions exist.
