Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492378, here are decompositions:

7 + 2147492371 = 2147492378
61 + 2147492317 = 2147492378
79 + 2147492299 = 2147492378
139 + 2147492239 = 2147492378
349 + 2147492029 = 2147492378
541 + 2147491837 = 2147492378
547 + 2147491831 = 2147492378
769 + 2147491609 = 2147492378

Showing the first eight; more decompositions exist.
