Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504506, here are decompositions:

13 + 31504493 = 31504506
53 + 31504453 = 31504506
67 + 31504439 = 31504506
139 + 31504367 = 31504506
149 + 31504357 = 31504506
179 + 31504327 = 31504506
277 + 31504229 = 31504506
317 + 31504189 = 31504506

Showing the first eight; more decompositions exist.
