Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460430, here are decompositions:

17 + 31460413 = 31460430
31 + 31460399 = 31460430
61 + 31460369 = 31460430
83 + 31460347 = 31460430
101 + 31460329 = 31460430
109 + 31460321 = 31460430
137 + 31460293 = 31460430
139 + 31460291 = 31460430

Showing the first eight; more decompositions exist.
