Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491682, here are decompositions:

73 + 2147491609 = 2147491682
79 + 2147491603 = 2147491682
109 + 2147491573 = 2147491682
139 + 2147491543 = 2147491682
313 + 2147491369 = 2147491682
409 + 2147491273 = 2147491682
421 + 2147491261 = 2147491682
433 + 2147491249 = 2147491682

Showing the first eight; more decompositions exist.
