Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488550, here are decompositions:

7 + 2147488543 = 2147488550
139 + 2147488411 = 2147488550
271 + 2147488279 = 2147488550
379 + 2147488171 = 2147488550
397 + 2147488153 = 2147488550
439 + 2147488111 = 2147488550
523 + 2147488027 = 2147488550
541 + 2147488009 = 2147488550

Showing the first eight; more decompositions exist.
