Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502954, here are decompositions:

13 + 31502941 = 31502954
31 + 31502923 = 31502954
73 + 31502881 = 31502954
97 + 31502857 = 31502954
193 + 31502761 = 31502954
211 + 31502743 = 31502954
367 + 31502587 = 31502954
397 + 31502557 = 31502954

Showing the first eight; more decompositions exist.
