Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971990, here are decompositions:

47 + 4294971943 = 4294971990
53 + 4294971937 = 4294971990
59 + 4294971931 = 4294971990
61 + 4294971929 = 4294971990
107 + 4294971883 = 4294971990
131 + 4294971859 = 4294971990
149 + 4294971841 = 4294971990
317 + 4294971673 = 4294971990

Showing the first eight; more decompositions exist.
