Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10430, here are decompositions:

3 + 10427 = 10430
31 + 10399 = 10430
61 + 10369 = 10430
73 + 10357 = 10430
97 + 10333 = 10430
109 + 10321 = 10430
127 + 10303 = 10430
157 + 10273 = 10430

Showing the first eight; more decompositions exist.
