Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553698, here are decompositions:

89 + 31553609 = 31553698
179 + 31553519 = 31553698
311 + 31553387 = 31553698
347 + 31553351 = 31553698
359 + 31553339 = 31553698
419 + 31553279 = 31553698
479 + 31553219 = 31553698
521 + 31553177 = 31553698

Showing the first eight; more decompositions exist.
