Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459598, here are decompositions:

199 + 31459399 = 31459598
211 + 31459387 = 31459598
241 + 31459357 = 31459598
277 + 31459321 = 31459598
307 + 31459291 = 31459598
337 + 31459261 = 31459598
397 + 31459201 = 31459598
487 + 31459111 = 31459598

Showing the first eight; more decompositions exist.
