Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619542, here are decompositions:

3 + 8619539 = 8619542
31 + 8619511 = 8619542
73 + 8619469 = 8619542
103 + 8619439 = 8619542
109 + 8619433 = 8619542
199 + 8619343 = 8619542
313 + 8619229 = 8619542
331 + 8619211 = 8619542

Showing the first eight; more decompositions exist.
