Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449602, here are decompositions:

13 + 31449589 = 31449602
31 + 31449571 = 31449602
103 + 31449499 = 31449602
109 + 31449493 = 31449602
139 + 31449463 = 31449602
181 + 31449421 = 31449602
193 + 31449409 = 31449602
199 + 31449403 = 31449602

Showing the first eight; more decompositions exist.
