Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624502, here are decompositions:

73 + 31624429 = 31624502
79 + 31624423 = 31624502
139 + 31624363 = 31624502
163 + 31624339 = 31624502
181 + 31624321 = 31624502
373 + 31624129 = 31624502
433 + 31624069 = 31624502
499 + 31624003 = 31624502

Showing the first eight; more decompositions exist.
