Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731932, here are decompositions:

19 + 8731913 = 8731932
31 + 8731901 = 8731932
59 + 8731873 = 8731932
71 + 8731861 = 8731932
73 + 8731859 = 8731932
101 + 8731831 = 8731932
113 + 8731819 = 8731932
149 + 8731783 = 8731932

Showing the first eight; more decompositions exist.
