Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4630, here are decompositions:

47 + 4583 = 4630
83 + 4547 = 4630
107 + 4523 = 4630
113 + 4517 = 4630
137 + 4493 = 4630
149 + 4481 = 4630
167 + 4463 = 4630
173 + 4457 = 4630

Showing the first eight; more decompositions exist.
