Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501654, here are decompositions:

71 + 31501583 = 31501654
131 + 31501523 = 31501654
227 + 31501427 = 31501654
251 + 31501403 = 31501654
293 + 31501361 = 31501654
563 + 31501091 = 31501654
593 + 31501061 = 31501654
617 + 31501037 = 31501654

Showing the first eight; more decompositions exist.
