Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671288, here are decompositions:

137 + 8671151 = 8671288
191 + 8671097 = 8671288
257 + 8671031 = 8671288
281 + 8671007 = 8671288
347 + 8670941 = 8671288
401 + 8670887 = 8671288
419 + 8670869 = 8671288
677 + 8670611 = 8671288

Showing the first eight; more decompositions exist.
