Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534982, here are decompositions:

103 + 31534879 = 31534982
109 + 31534873 = 31534982
151 + 31534831 = 31534982
163 + 31534819 = 31534982
181 + 31534801 = 31534982
229 + 31534753 = 31534982
313 + 31534669 = 31534982
331 + 31534651 = 31534982

Showing the first eight; more decompositions exist.
