Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482762, here are decompositions:

19 + 31482743 = 31482762
53 + 31482709 = 31482762
79 + 31482683 = 31482762
131 + 31482631 = 31482762
149 + 31482613 = 31482762
163 + 31482599 = 31482762
193 + 31482569 = 31482762
211 + 31482551 = 31482762

Showing the first eight; more decompositions exist.
