Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492892, here are decompositions:

151 + 2147492741 = 2147492892
191 + 2147492701 = 2147492892
239 + 2147492653 = 2147492892
271 + 2147492621 = 2147492892
283 + 2147492609 = 2147492892
353 + 2147492539 = 2147492892
359 + 2147492533 = 2147492892
401 + 2147492491 = 2147492892

Showing the first eight; more decompositions exist.
