Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465424, here are decompositions:

7 + 31465417 = 31465424
61 + 31465363 = 31465424
103 + 31465321 = 31465424
181 + 31465243 = 31465424
241 + 31465183 = 31465424
271 + 31465153 = 31465424
313 + 31465111 = 31465424
421 + 31465003 = 31465424

Showing the first eight; more decompositions exist.
