Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701992, here are decompositions:

31 + 8701961 = 8701992
41 + 8701951 = 8701992
43 + 8701949 = 8701992
59 + 8701933 = 8701992
71 + 8701921 = 8701992
109 + 8701883 = 8701992
139 + 8701853 = 8701992
179 + 8701813 = 8701992

Showing the first eight; more decompositions exist.
