Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625340, here are decompositions:

37 + 31625303 = 31625340
59 + 31625281 = 31625340
79 + 31625261 = 31625340
191 + 31625149 = 31625340
193 + 31625147 = 31625340
281 + 31625059 = 31625340
283 + 31625057 = 31625340
389 + 31624951 = 31625340

Showing the first eight; more decompositions exist.
