Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506584, here are decompositions:

7 + 31506577 = 31506584
61 + 31506523 = 31506584
73 + 31506511 = 31506584
163 + 31506421 = 31506584
211 + 31506373 = 31506584
313 + 31506271 = 31506584
337 + 31506247 = 31506584
523 + 31506061 = 31506584

Showing the first eight; more decompositions exist.
