Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485844, here are decompositions:

3 + 2147485841 = 2147485844
37 + 2147485807 = 2147485844
157 + 2147485687 = 2147485844
271 + 2147485573 = 2147485844
277 + 2147485567 = 2147485844
397 + 2147485447 = 2147485844
421 + 2147485423 = 2147485844
433 + 2147485411 = 2147485844

Showing the first eight; more decompositions exist.
