Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534496, here are decompositions:

3 + 31534493 = 31534496
13 + 31534483 = 31534496
67 + 31534429 = 31534496
73 + 31534423 = 31534496
127 + 31534369 = 31534496
163 + 31534333 = 31534496
199 + 31534297 = 31534496
313 + 31534183 = 31534496

Showing the first eight; more decompositions exist.
