Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485142, here are decompositions:

151 + 2147484991 = 2147485142
181 + 2147484961 = 2147485142
193 + 2147484949 = 2147485142
223 + 2147484919 = 2147485142
409 + 2147484733 = 2147485142
421 + 2147484721 = 2147485142
463 + 2147484679 = 2147485142
541 + 2147484601 = 2147485142

Showing the first eight; more decompositions exist.
