Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480582, here are decompositions:

53 + 31480529 = 31480582
149 + 31480433 = 31480582
191 + 31480391 = 31480582
233 + 31480349 = 31480582
293 + 31480289 = 31480582
479 + 31480103 = 31480582
491 + 31480091 = 31480582
503 + 31480079 = 31480582

Showing the first eight; more decompositions exist.
