Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461758, here are decompositions:

61 + 31461697 = 31461758
241 + 31461517 = 31461758
271 + 31461487 = 31461758
277 + 31461481 = 31461758
331 + 31461427 = 31461758
397 + 31461361 = 31461758
409 + 31461349 = 31461758
457 + 31461301 = 31461758

Showing the first eight; more decompositions exist.
