Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703972, here are decompositions:

29 + 8703943 = 8703972
61 + 8703911 = 8703972
73 + 8703899 = 8703972
83 + 8703889 = 8703972
113 + 8703859 = 8703972
131 + 8703841 = 8703972
139 + 8703833 = 8703972
149 + 8703823 = 8703972

Showing the first eight; more decompositions exist.
