Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625376, here are decompositions:

73 + 31625303 = 31625376
113 + 31625263 = 31625376
197 + 31625179 = 31625376
227 + 31625149 = 31625376
229 + 31625147 = 31625376
317 + 31625059 = 31625376
337 + 31625039 = 31625376
397 + 31624979 = 31625376

Showing the first eight; more decompositions exist.
