Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536434, here are decompositions:

31 + 31536403 = 31536434
37 + 31536397 = 31536434
43 + 31536391 = 31536434
73 + 31536361 = 31536434
211 + 31536223 = 31536434
337 + 31536097 = 31536434
373 + 31536061 = 31536434
487 + 31535947 = 31536434

Showing the first eight; more decompositions exist.
