Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731500, here are decompositions:

7 + 8731493 = 8731500
23 + 8731477 = 8731500
53 + 8731447 = 8731500
67 + 8731433 = 8731500
73 + 8731427 = 8731500
83 + 8731417 = 8731500
131 + 8731369 = 8731500
137 + 8731363 = 8731500

Showing the first eight; more decompositions exist.
