Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731028, here are decompositions:

79 + 8730949 = 8731028
109 + 8730919 = 8731028
127 + 8730901 = 8731028
139 + 8730889 = 8731028
181 + 8730847 = 8731028
331 + 8730697 = 8731028
337 + 8730691 = 8731028
367 + 8730661 = 8731028

Showing the first eight; more decompositions exist.
