Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553604, here are decompositions:

101 + 31553503 = 31553604
151 + 31553453 = 31553604
283 + 31553321 = 31553604
331 + 31553273 = 31553604
421 + 31553183 = 31553604
443 + 31553161 = 31553604
541 + 31553063 = 31553604
587 + 31553017 = 31553604

Showing the first eight; more decompositions exist.
