Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731206, here are decompositions:

5 + 8731201 = 8731206
19 + 8731187 = 8731206
53 + 8731153 = 8731206
67 + 8731139 = 8731206
97 + 8731109 = 8731206
103 + 8731103 = 8731206
109 + 8731097 = 8731206
137 + 8731069 = 8731206

Showing the first eight; more decompositions exist.
