Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705564, here are decompositions:

3 + 8705561 = 8705564
13 + 8705551 = 8705564
37 + 8705527 = 8705564
73 + 8705491 = 8705564
97 + 8705467 = 8705564
103 + 8705461 = 8705564
181 + 8705383 = 8705564
397 + 8705167 = 8705564

Showing the first eight; more decompositions exist.
