Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701990, here are decompositions:

29 + 8701961 = 8701990
41 + 8701949 = 8701990
83 + 8701907 = 8701990
107 + 8701883 = 8701990
113 + 8701877 = 8701990
137 + 8701853 = 8701990
179 + 8701811 = 8701990
233 + 8701757 = 8701990

Showing the first eight; more decompositions exist.
