Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527584, here are decompositions:

7 + 31527577 = 31527584
43 + 31527541 = 31527584
61 + 31527523 = 31527584
103 + 31527481 = 31527584
241 + 31527343 = 31527584
307 + 31527277 = 31527584
331 + 31527253 = 31527584
337 + 31527247 = 31527584

Showing the first eight; more decompositions exist.
