Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731490, here are decompositions:

13 + 8731477 = 8731490
43 + 8731447 = 8731490
73 + 8731417 = 8731490
109 + 8731381 = 8731490
127 + 8731363 = 8731490
151 + 8731339 = 8731490
181 + 8731309 = 8731490
241 + 8731249 = 8731490

Showing the first eight; more decompositions exist.
