Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295021538, here are decompositions:

107 + 4295021431 = 4295021538
179 + 4295021359 = 4295021538
191 + 4295021347 = 4295021538
211 + 4295021327 = 4295021538
257 + 4295021281 = 4295021538
317 + 4295021221 = 4295021538
331 + 4295021207 = 4295021538
491 + 4295021047 = 4295021538

Showing the first eight; more decompositions exist.
