Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74780, here are decompositions:

19 + 74761 = 74780
61 + 74719 = 74780
67 + 74713 = 74780
73 + 74707 = 74780
127 + 74653 = 74780
157 + 74623 = 74780
193 + 74587 = 74780
229 + 74551 = 74780

Showing the first eight; more decompositions exist.
