Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502532, here are decompositions:

43 + 31502489 = 31502532
73 + 31502459 = 31502532
101 + 31502431 = 31502532
179 + 31502353 = 31502532
199 + 31502333 = 31502532
263 + 31502269 = 31502532
349 + 31502183 = 31502532
401 + 31502131 = 31502532

Showing the first eight; more decompositions exist.
