Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461662, here are decompositions:

109 + 31461553 = 31461662
139 + 31461523 = 31461662
181 + 31461481 = 31461662
313 + 31461349 = 31461662
409 + 31461253 = 31461662
433 + 31461229 = 31461662
439 + 31461223 = 31461662
499 + 31461163 = 31461662

Showing the first eight; more decompositions exist.
