Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502392, here are decompositions:

29 + 31502363 = 31502392
59 + 31502333 = 31502392
113 + 31502279 = 31502392
149 + 31502243 = 31502392
179 + 31502213 = 31502392
263 + 31502129 = 31502392
293 + 31502099 = 31502392
479 + 31501913 = 31502392

Showing the first eight; more decompositions exist.
