Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744380, here are decompositions:

83 + 8744297 = 8744380
137 + 8744243 = 8744380
173 + 8744207 = 8744380
191 + 8744189 = 8744380
251 + 8744129 = 8744380
317 + 8744063 = 8744380
347 + 8744033 = 8744380
383 + 8743997 = 8744380

Showing the first eight; more decompositions exist.
