Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460634, here are decompositions:

53 + 31460581 = 31460634
83 + 31460551 = 31460634
97 + 31460537 = 31460634
137 + 31460497 = 31460634
151 + 31460483 = 31460634
193 + 31460441 = 31460634
313 + 31460321 = 31460634
353 + 31460281 = 31460634

Showing the first eight; more decompositions exist.
