Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502602, here are decompositions:

41 + 31502561 = 31502602
113 + 31502489 = 31502602
239 + 31502363 = 31502602
269 + 31502333 = 31502602
359 + 31502243 = 31502602
389 + 31502213 = 31502602
419 + 31502183 = 31502602
503 + 31502099 = 31502602

Showing the first eight; more decompositions exist.
