Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648626, here are decompositions:

83 + 8648543 = 8648626
89 + 8648537 = 8648626
113 + 8648513 = 8648626
167 + 8648459 = 8648626
179 + 8648447 = 8648626
257 + 8648369 = 8648626
293 + 8648333 = 8648626
359 + 8648267 = 8648626

Showing the first eight; more decompositions exist.
