Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554954, here are decompositions:

5 + 31554949 = 31554954
7 + 31554947 = 31554954
61 + 31554893 = 31554954
71 + 31554883 = 31554954
103 + 31554851 = 31554954
113 + 31554841 = 31554954
131 + 31554823 = 31554954
157 + 31554797 = 31554954

Showing the first eight; more decompositions exist.
