Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744820, here are decompositions:

83 + 8744737 = 8744820
103 + 8744717 = 8744820
109 + 8744711 = 8744820
113 + 8744707 = 8744820
137 + 8744683 = 8744820
157 + 8744663 = 8744820
193 + 8744627 = 8744820
257 + 8744563 = 8744820

Showing the first eight; more decompositions exist.
