Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553602, here are decompositions:

83 + 31553519 = 31553602
149 + 31553453 = 31553602
233 + 31553369 = 31553602
251 + 31553351 = 31553602
263 + 31553339 = 31553602
281 + 31553321 = 31553602
383 + 31553219 = 31553602
389 + 31553213 = 31553602

Showing the first eight; more decompositions exist.
