Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535632, here are decompositions:

41 + 31535591 = 31535632
83 + 31535549 = 31535632
251 + 31535381 = 31535632
311 + 31535321 = 31535632
419 + 31535213 = 31535632
449 + 31535183 = 31535632
461 + 31535171 = 31535632
509 + 31535123 = 31535632

Showing the first eight; more decompositions exist.
