Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609264, here are decompositions:

41 + 31609223 = 31609264
173 + 31609091 = 31609264
233 + 31609031 = 31609264
293 + 31608971 = 31609264
311 + 31608953 = 31609264
347 + 31608917 = 31609264
353 + 31608911 = 31609264
443 + 31608821 = 31609264

Showing the first eight; more decompositions exist.
