Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589054, here are decompositions:

37 + 31589017 = 31589054
43 + 31589011 = 31589054
61 + 31588993 = 31589054
97 + 31588957 = 31589054
103 + 31588951 = 31589054
127 + 31588927 = 31589054
157 + 31588897 = 31589054
241 + 31588813 = 31589054

Showing the first eight; more decompositions exist.
