Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565374, here are decompositions:

23 + 31565351 = 31565374
83 + 31565291 = 31565374
167 + 31565207 = 31565374
257 + 31565117 = 31565374
317 + 31565057 = 31565374
383 + 31564991 = 31565374
431 + 31564943 = 31565374
521 + 31564853 = 31565374

Showing the first eight; more decompositions exist.
