Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461654, here are decompositions:

13 + 31461641 = 31461654
83 + 31461571 = 31461654
97 + 31461557 = 31461654
101 + 31461553 = 31461654
131 + 31461523 = 31461654
137 + 31461517 = 31461654
167 + 31461487 = 31461654
173 + 31461481 = 31461654

Showing the first eight; more decompositions exist.
