Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958438, here are decompositions:

37 + 4294958401 = 4294958438
109 + 4294958329 = 4294958438
157 + 4294958281 = 4294958438
181 + 4294958257 = 4294958438
241 + 4294958197 = 4294958438
307 + 4294958131 = 4294958438
367 + 4294958071 = 4294958438
499 + 4294957939 = 4294958438

Showing the first eight; more decompositions exist.
