Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744772, here are decompositions:

61 + 8744711 = 8744772
89 + 8744683 = 8744772
109 + 8744663 = 8744772
173 + 8744599 = 8744772
313 + 8744459 = 8744772
349 + 8744423 = 8744772
353 + 8744419 = 8744772
359 + 8744413 = 8744772

Showing the first eight; more decompositions exist.
