Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459392, here are decompositions:

5 + 31459387 = 31459392
43 + 31459349 = 31459392
53 + 31459339 = 31459392
71 + 31459321 = 31459392
101 + 31459291 = 31459392
103 + 31459289 = 31459392
131 + 31459261 = 31459392
191 + 31459201 = 31459392

Showing the first eight; more decompositions exist.
