Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737144, here are decompositions:

5 + 8737139 = 8737144
47 + 8737097 = 8737144
71 + 8737073 = 8737144
83 + 8737061 = 8737144
233 + 8736911 = 8737144
263 + 8736881 = 8737144
443 + 8736701 = 8737144
461 + 8736683 = 8737144

Showing the first eight; more decompositions exist.
