Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534482, here are decompositions:

41 + 31534441 = 31534482
53 + 31534429 = 31534482
59 + 31534423 = 31534482
71 + 31534411 = 31534482
113 + 31534369 = 31534482
139 + 31534343 = 31534482
149 + 31534333 = 31534482
181 + 31534301 = 31534482

Showing the first eight; more decompositions exist.
