Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723524, here are decompositions:

3 + 8723521 = 8723524
41 + 8723483 = 8723524
83 + 8723441 = 8723524
101 + 8723423 = 8723524
137 + 8723387 = 8723524
281 + 8723243 = 8723524
311 + 8723213 = 8723524
401 + 8723123 = 8723524

Showing the first eight; more decompositions exist.
