Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455092, here are decompositions:

61 + 31455031 = 31455092
139 + 31454953 = 31455092
211 + 31454881 = 31455092
283 + 31454809 = 31455092
439 + 31454653 = 31455092
631 + 31454461 = 31455092
661 + 31454431 = 31455092
709 + 31454383 = 31455092

Showing the first eight; more decompositions exist.
