Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530058, here are decompositions:

29 + 31530029 = 31530058
41 + 31530017 = 31530058
89 + 31529969 = 31530058
167 + 31529891 = 31530058
239 + 31529819 = 31530058
389 + 31529669 = 31530058
491 + 31529567 = 31530058
587 + 31529471 = 31530058

Showing the first eight; more decompositions exist.
