Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465454, here are decompositions:

3 + 31465451 = 31465454
37 + 31465417 = 31465454
211 + 31465243 = 31465454
271 + 31465183 = 31465454
277 + 31465177 = 31465454
331 + 31465123 = 31465454
421 + 31465033 = 31465454
463 + 31464991 = 31465454

Showing the first eight; more decompositions exist.
