Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534542, here are decompositions:

41 + 31534501 = 31534542
59 + 31534483 = 31534542
101 + 31534441 = 31534542
113 + 31534429 = 31534542
131 + 31534411 = 31534542
173 + 31534369 = 31534542
199 + 31534343 = 31534542
241 + 31534301 = 31534542

Showing the first eight; more decompositions exist.
