Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658408, here are decompositions:

37 + 8658371 = 8658408
79 + 8658329 = 8658408
131 + 8658277 = 8658408
191 + 8658217 = 8658408
271 + 8658137 = 8658408
307 + 8658101 = 8658408
349 + 8658059 = 8658408
439 + 8657969 = 8658408

Showing the first eight; more decompositions exist.
