Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534526, here are decompositions:

43 + 31534483 = 31534526
97 + 31534429 = 31534526
103 + 31534423 = 31534526
157 + 31534369 = 31534526
193 + 31534333 = 31534526
229 + 31534297 = 31534526
409 + 31534117 = 31534526
547 + 31533979 = 31534526

Showing the first eight; more decompositions exist.
