Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589814, here are decompositions:

37 + 31589777 = 31589814
41 + 31589773 = 31589814
43 + 31589771 = 31589814
83 + 31589731 = 31589814
103 + 31589711 = 31589814
107 + 31589707 = 31589814
131 + 31589683 = 31589814
181 + 31589633 = 31589814

Showing the first eight; more decompositions exist.
