Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459542, here are decompositions:

43 + 31459499 = 31459542
109 + 31459433 = 31459542
193 + 31459349 = 31459542
199 + 31459343 = 31459542
251 + 31459291 = 31459542
281 + 31459261 = 31459542
409 + 31459133 = 31459542
419 + 31459123 = 31459542

Showing the first eight; more decompositions exist.
