Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580092, here are decompositions:

29 + 31580063 = 31580092
41 + 31580051 = 31580092
83 + 31580009 = 31580092
179 + 31579913 = 31580092
233 + 31579859 = 31580092
239 + 31579853 = 31580092
353 + 31579739 = 31580092
389 + 31579703 = 31580092

Showing the first eight; more decompositions exist.
