Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459482, here are decompositions:

73 + 31459409 = 31459482
83 + 31459399 = 31459482
139 + 31459343 = 31459482
191 + 31459291 = 31459482
193 + 31459289 = 31459482
281 + 31459201 = 31459482
283 + 31459199 = 31459482
331 + 31459151 = 31459482

Showing the first eight; more decompositions exist.
