Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492038, here are decompositions:

101 + 2147491937 = 2147492038
257 + 2147491781 = 2147492038
281 + 2147491757 = 2147492038
347 + 2147491691 = 2147492038
431 + 2147491607 = 2147492038
479 + 2147491559 = 2147492038
491 + 2147491547 = 2147492038
521 + 2147491517 = 2147492038

Showing the first eight; more decompositions exist.
