Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534436, here are decompositions:

7 + 31534429 = 31534436
13 + 31534423 = 31534436
67 + 31534369 = 31534436
103 + 31534333 = 31534436
139 + 31534297 = 31534436
379 + 31534057 = 31534436
457 + 31533979 = 31534436
487 + 31533949 = 31534436

Showing the first eight; more decompositions exist.
