Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661544, here are decompositions:

53 + 8661491 = 8661544
83 + 8661461 = 8661544
107 + 8661437 = 8661544
131 + 8661413 = 8661544
137 + 8661407 = 8661544
191 + 8661353 = 8661544
233 + 8661311 = 8661544
263 + 8661281 = 8661544

Showing the first eight; more decompositions exist.
