Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625252, here are decompositions:

73 + 31625179 = 31625252
103 + 31625149 = 31625252
193 + 31625059 = 31625252
313 + 31624939 = 31625252
331 + 31624921 = 31625252
499 + 31624753 = 31625252
613 + 31624639 = 31625252
661 + 31624591 = 31625252

Showing the first eight; more decompositions exist.
