Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483378, here are decompositions:

109 + 2147483269 = 2147483378
199 + 2147483179 = 2147483378
241 + 2147483137 = 2147483378
349 + 2147483029 = 2147483378
457 + 2147482921 = 2147483378
577 + 2147482801 = 2147483378
757 + 2147482621 = 2147483378
787 + 2147482591 = 2147483378

Showing the first eight; more decompositions exist.
