Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459362, here are decompositions:

5 + 31459357 = 31459362
13 + 31459349 = 31459362
19 + 31459343 = 31459362
23 + 31459339 = 31459362
41 + 31459321 = 31459362
71 + 31459291 = 31459362
73 + 31459289 = 31459362
101 + 31459261 = 31459362

Showing the first eight; more decompositions exist.
