Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459224, here are decompositions:

7 + 31459217 = 31459224
23 + 31459201 = 31459224
73 + 31459151 = 31459224
101 + 31459123 = 31459224
113 + 31459111 = 31459224
131 + 31459093 = 31459224
151 + 31459073 = 31459224
193 + 31459031 = 31459224

Showing the first eight; more decompositions exist.
