Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501302, here are decompositions:

71 + 31501231 = 31501302
73 + 31501229 = 31501302
83 + 31501219 = 31501302
101 + 31501201 = 31501302
103 + 31501199 = 31501302
211 + 31501091 = 31501302
241 + 31501061 = 31501302
263 + 31501039 = 31501302

Showing the first eight; more decompositions exist.
