Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488148, here are decompositions:

37 + 2147488111 = 2147488148
139 + 2147488009 = 2147488148
241 + 2147487907 = 2147488148
277 + 2147487871 = 2147488148
331 + 2147487817 = 2147488148
349 + 2147487799 = 2147488148
367 + 2147487781 = 2147488148
397 + 2147487751 = 2147488148

Showing the first eight; more decompositions exist.
