Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761582, here are decompositions:

113 + 8761469 = 8761582
149 + 8761433 = 8761582
293 + 8761289 = 8761582
443 + 8761139 = 8761582
449 + 8761133 = 8761582
503 + 8761079 = 8761582
563 + 8761019 = 8761582
659 + 8760923 = 8761582

Showing the first eight; more decompositions exist.
