Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534550, here are decompositions:

7 + 31534543 = 31534550
67 + 31534483 = 31534550
109 + 31534441 = 31534550
127 + 31534423 = 31534550
139 + 31534411 = 31534550
181 + 31534369 = 31534550
367 + 31534183 = 31534550
409 + 31534141 = 31534550

Showing the first eight; more decompositions exist.
