Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735140, here are decompositions:

3 + 8735137 = 8735140
101 + 8735039 = 8735140
257 + 8734883 = 8735140
317 + 8734823 = 8735140
383 + 8734757 = 8735140
443 + 8734697 = 8735140
563 + 8734577 = 8735140
569 + 8734571 = 8735140

Showing the first eight; more decompositions exist.
