Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498182, here are decompositions:

31 + 31498151 = 31498182
59 + 31498123 = 31498182
71 + 31498111 = 31498182
113 + 31498069 = 31498182
139 + 31498043 = 31498182
173 + 31498009 = 31498182
179 + 31498003 = 31498182
241 + 31497941 = 31498182

Showing the first eight; more decompositions exist.
