Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648744, here are decompositions:

3 + 8648741 = 8648744
7 + 8648737 = 8648744
43 + 8648701 = 8648744
67 + 8648677 = 8648744
193 + 8648551 = 8648744
211 + 8648533 = 8648744
331 + 8648413 = 8648744
373 + 8648371 = 8648744

Showing the first eight; more decompositions exist.
