Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456994, here are decompositions:

67 + 31456927 = 31456994
103 + 31456891 = 31456994
397 + 31456597 = 31456994
463 + 31456531 = 31456994
757 + 31456237 = 31456994
991 + 31456003 = 31456994
1033 + 31455961 = 31456994
1093 + 31455901 = 31456994

Showing the first eight; more decompositions exist.
