Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987438, here are decompositions:

11 + 4294987427 = 4294987438
107 + 4294987331 = 4294987438
149 + 4294987289 = 4294987438
281 + 4294987157 = 4294987438
449 + 4294986989 = 4294987438
479 + 4294986959 = 4294987438
587 + 4294986851 = 4294987438
701 + 4294986737 = 4294987438

Showing the first eight; more decompositions exist.
