Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731184, here are decompositions:

31 + 8731153 = 8731184
43 + 8731141 = 8731184
73 + 8731111 = 8731184
157 + 8731027 = 8731184
271 + 8730913 = 8731184
283 + 8730901 = 8731184
337 + 8730847 = 8731184
487 + 8730697 = 8731184

Showing the first eight; more decompositions exist.
