Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738464, here are decompositions:

17 + 8738447 = 8738464
101 + 8738363 = 8738464
113 + 8738351 = 8738464
131 + 8738333 = 8738464
191 + 8738273 = 8738464
233 + 8738231 = 8738464
263 + 8738201 = 8738464
431 + 8738033 = 8738464

Showing the first eight; more decompositions exist.
