Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731574, here are decompositions:

3 + 8731571 = 8731574
43 + 8731531 = 8731574
73 + 8731501 = 8731574
97 + 8731477 = 8731574
127 + 8731447 = 8731574
157 + 8731417 = 8731574
193 + 8731381 = 8731574
211 + 8731363 = 8731574

Showing the first eight; more decompositions exist.
