Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625926, here are decompositions:

83 + 31625843 = 31625926
107 + 31625819 = 31625926
149 + 31625777 = 31625926
173 + 31625753 = 31625926
347 + 31625579 = 31625926
359 + 31625567 = 31625926
389 + 31625537 = 31625926
419 + 31625507 = 31625926

Showing the first eight; more decompositions exist.
