Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459626, here are decompositions:

5 + 31459621 = 31459626
7 + 31459619 = 31459626
17 + 31459609 = 31459626
73 + 31459553 = 31459626
109 + 31459517 = 31459626
127 + 31459499 = 31459626
139 + 31459487 = 31459626
193 + 31459433 = 31459626

Showing the first eight; more decompositions exist.
