Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459700, here are decompositions:

3 + 31459697 = 31459700
67 + 31459633 = 31459700
79 + 31459621 = 31459700
313 + 31459387 = 31459700
379 + 31459321 = 31459700
409 + 31459291 = 31459700
439 + 31459261 = 31459700
499 + 31459201 = 31459700

Showing the first eight; more decompositions exist.
