Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456598, here are decompositions:

67 + 31456531 = 31456598
97 + 31456501 = 31456598
157 + 31456441 = 31456598
307 + 31456291 = 31456598
379 + 31456219 = 31456598
499 + 31456099 = 31456598
577 + 31456021 = 31456598
709 + 31455889 = 31456598

Showing the first eight; more decompositions exist.
