Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502432, here are decompositions:

61 + 31502371 = 31502432
79 + 31502353 = 31502432
103 + 31502329 = 31502432
163 + 31502269 = 31502432
271 + 31502161 = 31502432
349 + 31502083 = 31502432
571 + 31501861 = 31502432
601 + 31501831 = 31502432

Showing the first eight; more decompositions exist.
