Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459452, here are decompositions:

19 + 31459433 = 31459452
43 + 31459409 = 31459452
53 + 31459399 = 31459452
103 + 31459349 = 31459452
109 + 31459343 = 31459452
113 + 31459339 = 31459452
131 + 31459321 = 31459452
163 + 31459289 = 31459452

Showing the first eight; more decompositions exist.
