Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502948, here are decompositions:

7 + 31502941 = 31502948
67 + 31502881 = 31502948
409 + 31502539 = 31502948
577 + 31502371 = 31502948
619 + 31502329 = 31502948
661 + 31502287 = 31502948
787 + 31502161 = 31502948
991 + 31501957 = 31502948

Showing the first eight; more decompositions exist.
