Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456060, here are decompositions:

47 + 31456013 = 31456060
101 + 31455959 = 31456060
113 + 31455947 = 31456060
131 + 31455929 = 31456060
191 + 31455869 = 31456060
239 + 31455821 = 31456060
257 + 31455803 = 31456060
347 + 31455713 = 31456060

Showing the first eight; more decompositions exist.
