Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476582, here are decompositions:

31 + 31476551 = 31476582
73 + 31476509 = 31476582
83 + 31476499 = 31476582
131 + 31476451 = 31476582
149 + 31476433 = 31476582
191 + 31476391 = 31476582
199 + 31476383 = 31476582
211 + 31476371 = 31476582

Showing the first eight; more decompositions exist.
