Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625546, here are decompositions:

37 + 31625509 = 31625546
79 + 31625467 = 31625546
163 + 31625383 = 31625546
283 + 31625263 = 31625546
367 + 31625179 = 31625546
397 + 31625149 = 31625546
487 + 31625059 = 31625546
607 + 31624939 = 31625546

Showing the first eight; more decompositions exist.
