Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534442, here are decompositions:

13 + 31534429 = 31534442
19 + 31534423 = 31534442
31 + 31534411 = 31534442
73 + 31534369 = 31534442
109 + 31534333 = 31534442
211 + 31534231 = 31534442
409 + 31534033 = 31534442
463 + 31533979 = 31534442

Showing the first eight; more decompositions exist.
