Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492988, here are decompositions:

29 + 2147492959 = 2147492988
59 + 2147492929 = 2147492988
229 + 2147492759 = 2147492988
317 + 2147492671 = 2147492988
349 + 2147492639 = 2147492988
367 + 2147492621 = 2147492988
379 + 2147492609 = 2147492988
397 + 2147492591 = 2147492988

Showing the first eight; more decompositions exist.
