Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 598, here are decompositions:

5 + 593 = 598
11 + 587 = 598
29 + 569 = 598
41 + 557 = 598
89 + 509 = 598
107 + 491 = 598
131 + 467 = 598
137 + 461 = 598

Showing the first eight; more decompositions exist.
