Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649130, here are decompositions:

59 + 8649071 = 8649130
101 + 8649029 = 8649130
107 + 8649023 = 8649130
251 + 8648879 = 8649130
263 + 8648867 = 8649130
293 + 8648837 = 8649130
317 + 8648813 = 8649130
383 + 8648747 = 8649130

Showing the first eight; more decompositions exist.
