Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482936, here are decompositions:

29 + 31482907 = 31482936
47 + 31482889 = 31482936
97 + 31482839 = 31482936
103 + 31482833 = 31482936
113 + 31482823 = 31482936
137 + 31482799 = 31482936
157 + 31482779 = 31482936
193 + 31482743 = 31482936

Showing the first eight; more decompositions exist.
