Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489580, here are decompositions:

37 + 2147489543 = 2147489580
43 + 2147489537 = 2147489580
97 + 2147489483 = 2147489580
107 + 2147489473 = 2147489580
139 + 2147489441 = 2147489580
157 + 2147489423 = 2147489580
179 + 2147489401 = 2147489580
233 + 2147489347 = 2147489580

Showing the first eight; more decompositions exist.
