Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488838, here are decompositions:

97 + 2147488741 = 2147488838
409 + 2147488429 = 2147488838
421 + 2147488417 = 2147488838
457 + 2147488381 = 2147488838
727 + 2147488111 = 2147488838
811 + 2147488027 = 2147488838
829 + 2147488009 = 2147488838
907 + 2147487931 = 2147488838

Showing the first eight; more decompositions exist.
