Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502608, here are decompositions:

47 + 31502561 = 31502608
149 + 31502459 = 31502608
167 + 31502441 = 31502608
419 + 31502189 = 31502608
461 + 31502147 = 31502608
479 + 31502129 = 31502608
509 + 31502099 = 31502608
701 + 31501907 = 31502608

Showing the first eight; more decompositions exist.
