Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461292, here are decompositions:

11 + 31461281 = 31461292
101 + 31461191 = 31461292
113 + 31461179 = 31461292
131 + 31461161 = 31461292
179 + 31461113 = 31461292
281 + 31461011 = 31461292
419 + 31460873 = 31461292
461 + 31460831 = 31461292

Showing the first eight; more decompositions exist.
