Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661832, here are decompositions:

89 + 8661743 = 8661832
149 + 8661683 = 8661832
191 + 8661641 = 8661832
251 + 8661581 = 8661832
353 + 8661479 = 8661832
419 + 8661413 = 8661832
449 + 8661383 = 8661832
479 + 8661353 = 8661832

Showing the first eight; more decompositions exist.
