Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732860, here are decompositions:

29 + 8732831 = 8732860
41 + 8732819 = 8732860
53 + 8732807 = 8732860
173 + 8732687 = 8732860
233 + 8732627 = 8732860
359 + 8732501 = 8732860
431 + 8732429 = 8732860
443 + 8732417 = 8732860

Showing the first eight; more decompositions exist.
