Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624342, here are decompositions:

3 + 31624339 = 31624342
5 + 31624337 = 31624342
11 + 31624331 = 31624342
59 + 31624283 = 31624342
353 + 31623989 = 31624342
359 + 31623983 = 31624342
383 + 31623959 = 31624342
389 + 31623953 = 31624342

Showing the first eight; more decompositions exist.
