Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502746, here are decompositions:

3 + 31502743 = 31502746
47 + 31502699 = 31502746
59 + 31502687 = 31502746
257 + 31502489 = 31502746
263 + 31502483 = 31502746
383 + 31502363 = 31502746
467 + 31502279 = 31502746
503 + 31502243 = 31502746

Showing the first eight; more decompositions exist.
