Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758180, here are decompositions:

23 + 8758157 = 8758180
113 + 8758067 = 8758180
131 + 8758049 = 8758180
173 + 8758007 = 8758180
359 + 8757821 = 8758180
461 + 8757719 = 8758180
467 + 8757713 = 8758180
479 + 8757701 = 8758180

Showing the first eight; more decompositions exist.
