Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547378, here are decompositions:

61 + 31547317 = 31547378
97 + 31547281 = 31547378
277 + 31547101 = 31547378
397 + 31546981 = 31547378
409 + 31546969 = 31547378
487 + 31546891 = 31547378
547 + 31546831 = 31547378
571 + 31546807 = 31547378

Showing the first eight; more decompositions exist.
