Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459202, here are decompositions:

3 + 31459199 = 31459202
79 + 31459123 = 31459202
109 + 31459093 = 31459202
139 + 31459063 = 31459202
373 + 31458829 = 31459202
499 + 31458703 = 31459202
571 + 31458631 = 31459202
601 + 31458601 = 31459202

Showing the first eight; more decompositions exist.
