Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465574, here are decompositions:

3 + 31465571 = 31465574
13 + 31465561 = 31465574
157 + 31465417 = 31465574
211 + 31465363 = 31465574
331 + 31465243 = 31465574
397 + 31465177 = 31465574
421 + 31465153 = 31465574
463 + 31465111 = 31465574

Showing the first eight; more decompositions exist.
