Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502626, here are decompositions:

137 + 31502489 = 31502626
167 + 31502459 = 31502626
263 + 31502363 = 31502626
293 + 31502333 = 31502626
347 + 31502279 = 31502626
383 + 31502243 = 31502626
443 + 31502183 = 31502626
479 + 31502147 = 31502626

Showing the first eight; more decompositions exist.
