Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705424, here are decompositions:

5 + 8705419 = 8705424
41 + 8705383 = 8705424
73 + 8705351 = 8705424
113 + 8705311 = 8705424
127 + 8705297 = 8705424
163 + 8705261 = 8705424
241 + 8705183 = 8705424
257 + 8705167 = 8705424

Showing the first eight; more decompositions exist.
