Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502334, here are decompositions:

5 + 31502329 = 31502334
23 + 31502311 = 31502334
47 + 31502287 = 31502334
151 + 31502183 = 31502334
173 + 31502161 = 31502334
251 + 31502083 = 31502334
397 + 31501937 = 31502334
421 + 31501913 = 31502334

Showing the first eight; more decompositions exist.
