Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480500, here are decompositions:

59 + 31480441 = 31480500
67 + 31480433 = 31480500
109 + 31480391 = 31480500
127 + 31480373 = 31480500
131 + 31480369 = 31480500
151 + 31480349 = 31480500
211 + 31480289 = 31480500
241 + 31480259 = 31480500

Showing the first eight; more decompositions exist.
