Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987180, here are decompositions:

23 + 4294987157 = 4294987180
191 + 4294986989 = 4294987180
227 + 4294986953 = 4294987180
269 + 4294986911 = 4294987180
317 + 4294986863 = 4294987180
443 + 4294986737 = 4294987180
479 + 4294986701 = 4294987180
683 + 4294986497 = 4294987180

Showing the first eight; more decompositions exist.
