Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618982, here are decompositions:

23 + 8618959 = 8618982
59 + 8618923 = 8618982
89 + 8618893 = 8618982
103 + 8618879 = 8618982
131 + 8618851 = 8618982
149 + 8618833 = 8618982
173 + 8618809 = 8618982
193 + 8618789 = 8618982

Showing the first eight; more decompositions exist.
