Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465514, here are decompositions:

97 + 31465417 = 31465514
151 + 31465363 = 31465514
193 + 31465321 = 31465514
271 + 31465243 = 31465514
331 + 31465183 = 31465514
337 + 31465177 = 31465514
523 + 31464991 = 31465514
541 + 31464973 = 31465514

Showing the first eight; more decompositions exist.
