Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744392, here are decompositions:

131 + 8744261 = 8744392
149 + 8744243 = 8744392
263 + 8744129 = 8744392
311 + 8744081 = 8744392
359 + 8744033 = 8744392
389 + 8744003 = 8744392
401 + 8743991 = 8744392
479 + 8743913 = 8744392

Showing the first eight; more decompositions exist.
