Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462048, here are decompositions:

41 + 31462007 = 31462048
71 + 31461977 = 31462048
197 + 31461851 = 31462048
257 + 31461791 = 31462048
269 + 31461779 = 31462048
311 + 31461737 = 31462048
479 + 31461569 = 31462048
491 + 31461557 = 31462048

Showing the first eight; more decompositions exist.
