Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545954, here are decompositions:

31 + 31545923 = 31545954
53 + 31545901 = 31545954
67 + 31545887 = 31545954
113 + 31545841 = 31545954
191 + 31545763 = 31545954
211 + 31545743 = 31545954
241 + 31545713 = 31545954
313 + 31545641 = 31545954

Showing the first eight; more decompositions exist.
