Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462684, here are decompositions:

101 + 31462583 = 31462684
107 + 31462577 = 31462684
131 + 31462553 = 31462684
137 + 31462547 = 31462684
233 + 31462451 = 31462684
251 + 31462433 = 31462684
311 + 31462373 = 31462684
467 + 31462217 = 31462684

Showing the first eight; more decompositions exist.
