Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580014, here are decompositions:

5 + 31580009 = 31580014
47 + 31579967 = 31580014
101 + 31579913 = 31580014
251 + 31579763 = 31580014
293 + 31579721 = 31580014
311 + 31579703 = 31580014
353 + 31579661 = 31580014
503 + 31579511 = 31580014

Showing the first eight; more decompositions exist.
