Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554602, here are decompositions:

19 + 31554583 = 31554602
31 + 31554571 = 31554602
61 + 31554541 = 31554602
109 + 31554493 = 31554602
139 + 31554463 = 31554602
193 + 31554409 = 31554602
241 + 31554361 = 31554602
421 + 31554181 = 31554602

Showing the first eight; more decompositions exist.
