Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459108, here are decompositions:

89 + 31459019 = 31459108
311 + 31458797 = 31459108
347 + 31458761 = 31459108
389 + 31458719 = 31459108
419 + 31458689 = 31459108
521 + 31458587 = 31459108
677 + 31458431 = 31459108
797 + 31458311 = 31459108

Showing the first eight; more decompositions exist.
