Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534844, here are decompositions:

13 + 31534831 = 31534844
43 + 31534801 = 31534844
193 + 31534651 = 31534844
283 + 31534561 = 31534844
421 + 31534423 = 31534844
433 + 31534411 = 31534844
547 + 31534297 = 31534844
613 + 31534231 = 31534844

Showing the first eight; more decompositions exist.
