Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589340, here are decompositions:

7 + 31589333 = 31589340
11 + 31589329 = 31589340
19 + 31589321 = 31589340
23 + 31589317 = 31589340
37 + 31589303 = 31589340
43 + 31589297 = 31589340
47 + 31589293 = 31589340
53 + 31589287 = 31589340

Showing the first eight; more decompositions exist.
