Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619972, here are decompositions:

29 + 8619943 = 8619972
79 + 8619893 = 8619972
89 + 8619883 = 8619972
103 + 8619869 = 8619972
113 + 8619859 = 8619972
181 + 8619791 = 8619972
199 + 8619773 = 8619972
311 + 8619661 = 8619972

Showing the first eight; more decompositions exist.
