Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459184, here are decompositions:

61 + 31459123 = 31459184
73 + 31459111 = 31459184
271 + 31458913 = 31459184
277 + 31458907 = 31459184
283 + 31458901 = 31459184
397 + 31458787 = 31459184
487 + 31458697 = 31459184
541 + 31458643 = 31459184

Showing the first eight; more decompositions exist.
