Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625192, here are decompositions:

13 + 31625179 = 31625192
43 + 31625149 = 31625192
61 + 31625131 = 31625192
241 + 31624951 = 31625192
271 + 31624921 = 31625192
331 + 31624861 = 31625192
409 + 31624783 = 31625192
439 + 31624753 = 31625192

Showing the first eight; more decompositions exist.
