Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492890, here are decompositions:

47 + 2147492843 = 2147492890
131 + 2147492759 = 2147492890
149 + 2147492741 = 2147492890
251 + 2147492639 = 2147492890
269 + 2147492621 = 2147492890
281 + 2147492609 = 2147492890
293 + 2147492597 = 2147492890
401 + 2147492489 = 2147492890

Showing the first eight; more decompositions exist.
