Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991620, here are decompositions:

41 + 4294991579 = 4294991620
113 + 4294991507 = 4294991620
149 + 4294991471 = 4294991620
173 + 4294991447 = 4294991620
191 + 4294991429 = 4294991620
197 + 4294991423 = 4294991620
233 + 4294991387 = 4294991620
263 + 4294991357 = 4294991620

Showing the first eight; more decompositions exist.
