Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482582, here are decompositions:

13 + 31482569 = 31482582
23 + 31482559 = 31482582
31 + 31482551 = 31482582
71 + 31482511 = 31482582
73 + 31482509 = 31482582
83 + 31482499 = 31482582
181 + 31482401 = 31482582
193 + 31482389 = 31482582

Showing the first eight; more decompositions exist.
