Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459946, here are decompositions:

97 + 31459849 = 31459946
139 + 31459807 = 31459946
223 + 31459723 = 31459946
229 + 31459717 = 31459946
313 + 31459633 = 31459946
337 + 31459609 = 31459946
547 + 31459399 = 31459946
607 + 31459339 = 31459946

Showing the first eight; more decompositions exist.
