Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731858, here are decompositions:

41 + 8731817 = 8731858
71 + 8731787 = 8731858
101 + 8731757 = 8731858
137 + 8731721 = 8731858
197 + 8731661 = 8731858
251 + 8731607 = 8731858
347 + 8731511 = 8731858
431 + 8731427 = 8731858

Showing the first eight; more decompositions exist.
