Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540058, here are decompositions:

127 + 31539931 = 31540058
157 + 31539901 = 31540058
241 + 31539817 = 31540058
331 + 31539727 = 31540058
397 + 31539661 = 31540058
409 + 31539649 = 31540058
619 + 31539439 = 31540058
691 + 31539367 = 31540058

Showing the first eight; more decompositions exist.
