Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748988, here are decompositions:

107 + 8748881 = 8748988
167 + 8748821 = 8748988
257 + 8748731 = 8748988
389 + 8748599 = 8748988
401 + 8748587 = 8748988
557 + 8748431 = 8748988
569 + 8748419 = 8748988
659 + 8748329 = 8748988

Showing the first eight; more decompositions exist.
