Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726190, here are decompositions:

47 + 8726143 = 8726190
89 + 8726101 = 8726190
97 + 8726093 = 8726190
103 + 8726087 = 8726190
127 + 8726063 = 8726190
139 + 8726051 = 8726190
163 + 8726027 = 8726190
173 + 8726017 = 8726190

Showing the first eight; more decompositions exist.
