Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492430, here are decompositions:

37 + 2147492393 = 2147492430
43 + 2147492387 = 2147492430
59 + 2147492371 = 2147492430
101 + 2147492329 = 2147492430
103 + 2147492327 = 2147492430
113 + 2147492317 = 2147492430
131 + 2147492299 = 2147492430
191 + 2147492239 = 2147492430

Showing the first eight; more decompositions exist.
