Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456274, here are decompositions:

37 + 31456237 = 31456274
151 + 31456123 = 31456274
181 + 31456093 = 31456274
271 + 31456003 = 31456274
313 + 31455961 = 31456274
373 + 31455901 = 31456274
397 + 31455877 = 31456274
433 + 31455841 = 31456274

Showing the first eight; more decompositions exist.
