Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461848, here are decompositions:

7 + 31461841 = 31461848
31 + 31461817 = 31461848
37 + 31461811 = 31461848
151 + 31461697 = 31461848
277 + 31461571 = 31461848
331 + 31461517 = 31461848
367 + 31461481 = 31461848
421 + 31461427 = 31461848

Showing the first eight; more decompositions exist.
