Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493458, here are decompositions:

67 + 2147493391 = 2147493458
157 + 2147493301 = 2147493458
181 + 2147493277 = 2147493458
349 + 2147493109 = 2147493458
379 + 2147493079 = 2147493458
421 + 2147493037 = 2147493458
457 + 2147493001 = 2147493458
499 + 2147492959 = 2147493458

Showing the first eight; more decompositions exist.
