Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492058, here are decompositions:

7 + 31492051 = 31492058
271 + 31491787 = 31492058
331 + 31491727 = 31492058
379 + 31491679 = 31492058
397 + 31491661 = 31492058
421 + 31491637 = 31492058
439 + 31491619 = 31492058
487 + 31491571 = 31492058

Showing the first eight; more decompositions exist.
