Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625348, here are decompositions:

67 + 31625281 = 31625348
199 + 31625149 = 31625348
397 + 31624951 = 31625348
409 + 31624939 = 31625348
421 + 31624927 = 31625348
487 + 31624861 = 31625348
499 + 31624849 = 31625348
541 + 31624807 = 31625348

Showing the first eight; more decompositions exist.
