Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558058, here are decompositions:

19 + 31558039 = 31558058
61 + 31557997 = 31558058
97 + 31557961 = 31558058
127 + 31557931 = 31558058
139 + 31557919 = 31558058
271 + 31557787 = 31558058
409 + 31557649 = 31558058
421 + 31557637 = 31558058

Showing the first eight; more decompositions exist.
