Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498152, here are decompositions:

29 + 31498123 = 31498152
41 + 31498111 = 31498152
83 + 31498069 = 31498152
109 + 31498043 = 31498152
113 + 31498039 = 31498152
149 + 31498003 = 31498152
173 + 31497979 = 31498152
211 + 31497941 = 31498152

Showing the first eight; more decompositions exist.
