Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731902, here are decompositions:

29 + 8731873 = 8731902
41 + 8731861 = 8731902
43 + 8731859 = 8731902
71 + 8731831 = 8731902
83 + 8731819 = 8731902
139 + 8731763 = 8731902
181 + 8731721 = 8731902
191 + 8731711 = 8731902

Showing the first eight; more decompositions exist.
