Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705372, here are decompositions:

3 + 8705369 = 8705372
61 + 8705311 = 8705372
73 + 8705299 = 8705372
103 + 8705269 = 8705372
223 + 8705149 = 8705372
331 + 8705041 = 8705372
421 + 8704951 = 8705372
463 + 8704909 = 8705372

Showing the first eight; more decompositions exist.
