Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751988, here are decompositions:

101 + 8751887 = 8751988
149 + 8751839 = 8751988
239 + 8751749 = 8751988
317 + 8751671 = 8751988
359 + 8751629 = 8751988
389 + 8751599 = 8751988
431 + 8751557 = 8751988
461 + 8751527 = 8751988

Showing the first eight; more decompositions exist.
