Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462208, here are decompositions:

67 + 31462141 = 31462208
139 + 31462069 = 31462208
229 + 31461979 = 31462208
367 + 31461841 = 31462208
397 + 31461811 = 31462208
691 + 31461517 = 31462208
727 + 31461481 = 31462208
751 + 31461457 = 31462208

Showing the first eight; more decompositions exist.
