Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702138, here are decompositions:

7 + 8702131 = 8702138
31 + 8702107 = 8702138
139 + 8701999 = 8702138
349 + 8701789 = 8702138
397 + 8701741 = 8702138
409 + 8701729 = 8702138
607 + 8701531 = 8702138
619 + 8701519 = 8702138

Showing the first eight; more decompositions exist.
