Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462664, here are decompositions:

61 + 31462603 = 31462664
73 + 31462591 = 31462664
157 + 31462507 = 31462664
193 + 31462471 = 31462664
223 + 31462441 = 31462664
283 + 31462381 = 31462664
307 + 31462357 = 31462664
313 + 31462351 = 31462664

Showing the first eight; more decompositions exist.
