Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618994, here are decompositions:

61 + 8618933 = 8618994
71 + 8618923 = 8618994
101 + 8618893 = 8618994
127 + 8618867 = 8618994
211 + 8618783 = 8618994
257 + 8618737 = 8618994
311 + 8618683 = 8618994
313 + 8618681 = 8618994

Showing the first eight; more decompositions exist.
