Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619740, here are decompositions:

79 + 8619661 = 8619740
139 + 8619601 = 8619740
229 + 8619511 = 8619740
271 + 8619469 = 8619740
307 + 8619433 = 8619740
313 + 8619427 = 8619740
397 + 8619343 = 8619740
499 + 8619241 = 8619740

Showing the first eight; more decompositions exist.
