Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465598, here are decompositions:

19 + 31465579 = 31465598
37 + 31465561 = 31465598
139 + 31465459 = 31465598
181 + 31465417 = 31465598
277 + 31465321 = 31465598
421 + 31465177 = 31465598
487 + 31465111 = 31465598
499 + 31465099 = 31465598

Showing the first eight; more decompositions exist.
