Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620482, here are decompositions:

73 + 31620409 = 31620482
139 + 31620343 = 31620482
181 + 31620301 = 31620482
331 + 31620151 = 31620482
373 + 31620109 = 31620482
463 + 31620019 = 31620482
571 + 31619911 = 31620482
613 + 31619869 = 31620482

Showing the first eight; more decompositions exist.
