Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553692, here are decompositions:

29 + 31553663 = 31553692
83 + 31553609 = 31553692
173 + 31553519 = 31553692
239 + 31553453 = 31553692
353 + 31553339 = 31553692
419 + 31553273 = 31553692
431 + 31553261 = 31553692
479 + 31553213 = 31553692

Showing the first eight; more decompositions exist.
