Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731860, here are decompositions:

29 + 8731831 = 8731860
41 + 8731819 = 8731860
43 + 8731817 = 8731860
73 + 8731787 = 8731860
83 + 8731777 = 8731860
97 + 8731763 = 8731860
103 + 8731757 = 8731860
139 + 8731721 = 8731860

Showing the first eight; more decompositions exist.
