Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490584, here are decompositions:

11 + 31490573 = 31490584
17 + 31490567 = 31490584
131 + 31490453 = 31490584
137 + 31490447 = 31490584
233 + 31490351 = 31490584
347 + 31490237 = 31490584
491 + 31490093 = 31490584
641 + 31489943 = 31490584

Showing the first eight; more decompositions exist.
