Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520462, here are decompositions:

73 + 31520389 = 31520462
109 + 31520353 = 31520462
163 + 31520299 = 31520462
229 + 31520233 = 31520462
283 + 31520179 = 31520462
373 + 31520089 = 31520462
433 + 31520029 = 31520462
619 + 31519843 = 31520462

Showing the first eight; more decompositions exist.
