Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536436, here are decompositions:

53 + 31536383 = 31536436
83 + 31536353 = 31536436
89 + 31536347 = 31536436
149 + 31536287 = 31536436
233 + 31536203 = 31536436
383 + 31536053 = 31536436
419 + 31536017 = 31536436
557 + 31535879 = 31536436

Showing the first eight; more decompositions exist.
