Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459492, here are decompositions:

5 + 31459487 = 31459492
59 + 31459433 = 31459492
83 + 31459409 = 31459492
149 + 31459343 = 31459492
269 + 31459223 = 31459492
293 + 31459199 = 31459492
359 + 31459133 = 31459492
419 + 31459073 = 31459492

Showing the first eight; more decompositions exist.
