Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456370, here are decompositions:

79 + 31456291 = 31456370
151 + 31456219 = 31456370
271 + 31456099 = 31456370
277 + 31456093 = 31456370
349 + 31456021 = 31456370
367 + 31456003 = 31456370
409 + 31455961 = 31456370
541 + 31455829 = 31456370

Showing the first eight; more decompositions exist.
