Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553342, here are decompositions:

3 + 31553339 = 31553342
109 + 31553233 = 31553342
181 + 31553161 = 31553342
463 + 31552879 = 31553342
661 + 31552681 = 31553342
739 + 31552603 = 31553342
853 + 31552489 = 31553342
991 + 31552351 = 31553342

Showing the first eight; more decompositions exist.
