Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551602, here are decompositions:

3 + 31551599 = 31551602
151 + 31551451 = 31551602
193 + 31551409 = 31551602
241 + 31551361 = 31551602
283 + 31551319 = 31551602
463 + 31551139 = 31551602
751 + 31550851 = 31551602
769 + 31550833 = 31551602

Showing the first eight; more decompositions exist.
