Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534562, here are decompositions:

19 + 31534543 = 31534562
61 + 31534501 = 31534562
79 + 31534483 = 31534562
139 + 31534423 = 31534562
151 + 31534411 = 31534562
193 + 31534369 = 31534562
229 + 31534333 = 31534562
331 + 31534231 = 31534562

Showing the first eight; more decompositions exist.
