Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620004, here are decompositions:

7 + 8619997 = 8620004
61 + 8619943 = 8620004
67 + 8619937 = 8620004
193 + 8619811 = 8620004
571 + 8619433 = 8620004
577 + 8619427 = 8620004
607 + 8619397 = 8620004
661 + 8619343 = 8620004

Showing the first eight; more decompositions exist.
