Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502792, here are decompositions:

31 + 31502761 = 31502792
103 + 31502689 = 31502792
229 + 31502563 = 31502792
421 + 31502371 = 31502792
439 + 31502353 = 31502792
463 + 31502329 = 31502792
523 + 31502269 = 31502792
631 + 31502161 = 31502792

Showing the first eight; more decompositions exist.
