Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502662, here are decompositions:

3 + 31502659 = 31502662
101 + 31502561 = 31502662
173 + 31502489 = 31502662
179 + 31502483 = 31502662
383 + 31502279 = 31502662
419 + 31502243 = 31502662
449 + 31502213 = 31502662
479 + 31502183 = 31502662

Showing the first eight; more decompositions exist.
