Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536524, here are decompositions:

3 + 31536521 = 31536524
43 + 31536481 = 31536524
127 + 31536397 = 31536524
163 + 31536361 = 31536524
211 + 31536313 = 31536524
337 + 31536187 = 31536524
463 + 31536061 = 31536524
541 + 31535983 = 31536524

Showing the first eight; more decompositions exist.
