Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294952778, here are decompositions:

29 + 4294952749 = 4294952778
59 + 4294952719 = 4294952778
79 + 4294952699 = 4294952778
101 + 4294952677 = 4294952778
131 + 4294952647 = 4294952778
139 + 4294952639 = 4294952778
349 + 4294952429 = 4294952778
359 + 4294952419 = 4294952778

Showing the first eight; more decompositions exist.
