Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553434, here are decompositions:

47 + 31553387 = 31553434
83 + 31553351 = 31553434
113 + 31553321 = 31553434
173 + 31553261 = 31553434
233 + 31553201 = 31553434
251 + 31553183 = 31553434
257 + 31553177 = 31553434
491 + 31552943 = 31553434

Showing the first eight; more decompositions exist.
