Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544526, here are decompositions:

17 + 31544509 = 31544526
109 + 31544417 = 31544526
163 + 31544363 = 31544526
179 + 31544347 = 31544526
229 + 31544297 = 31544526
313 + 31544213 = 31544526
337 + 31544189 = 31544526
347 + 31544179 = 31544526

Showing the first eight; more decompositions exist.
