Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977142, here are decompositions:

73 + 977069 = 977142
151 + 976991 = 977142
191 + 976951 = 977142
223 + 976919 = 977142
233 + 976909 = 977142
293 + 976849 = 977142
421 + 976721 = 977142
433 + 976709 = 977142

Showing the first eight; more decompositions exist.
