Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501346, here are decompositions:

13 + 31501333 = 31501346
43 + 31501303 = 31501346
127 + 31501219 = 31501346
229 + 31501117 = 31501346
307 + 31501039 = 31501346
337 + 31501009 = 31501346
367 + 31500979 = 31501346
379 + 31500967 = 31501346

Showing the first eight; more decompositions exist.
