Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618992, here are decompositions:

59 + 8618933 = 8618992
113 + 8618879 = 8618992
131 + 8618861 = 8618992
233 + 8618759 = 8618992
293 + 8618699 = 8618992
311 + 8618681 = 8618992
353 + 8618639 = 8618992
401 + 8618591 = 8618992

Showing the first eight; more decompositions exist.
