Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462618, here are decompositions:

29 + 31462589 = 31462618
41 + 31462577 = 31462618
71 + 31462547 = 31462618
137 + 31462481 = 31462618
167 + 31462451 = 31462618
179 + 31462439 = 31462618
269 + 31462349 = 31462618
401 + 31462217 = 31462618

Showing the first eight; more decompositions exist.
