Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502048, here are decompositions:

199 + 31501849 = 31502048
229 + 31501819 = 31502048
241 + 31501807 = 31502048
307 + 31501741 = 31502048
349 + 31501699 = 31502048
379 + 31501669 = 31502048
601 + 31501447 = 31502048
661 + 31501387 = 31502048

Showing the first eight; more decompositions exist.
