Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732020, here are decompositions:

29 + 8731991 = 8732020
41 + 8731979 = 8732020
83 + 8731937 = 8732020
107 + 8731913 = 8732020
113 + 8731907 = 8732020
233 + 8731787 = 8732020
257 + 8731763 = 8732020
263 + 8731757 = 8732020

Showing the first eight; more decompositions exist.
