Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625244, here are decompositions:

97 + 31625147 = 31625244
113 + 31625131 = 31625244
293 + 31624951 = 31625244
317 + 31624927 = 31625244
337 + 31624907 = 31625244
383 + 31624861 = 31625244
461 + 31624783 = 31625244
463 + 31624781 = 31625244

Showing the first eight; more decompositions exist.
