Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691090, here are decompositions:

47 + 8691043 = 8691090
71 + 8691019 = 8691090
127 + 8690963 = 8691090
131 + 8690959 = 8691090
137 + 8690953 = 8691090
139 + 8690951 = 8691090
173 + 8690917 = 8691090
223 + 8690867 = 8691090

Showing the first eight; more decompositions exist.
