Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472846, here are decompositions:

7 + 31472839 = 31472846
19 + 31472827 = 31472846
73 + 31472773 = 31472846
367 + 31472479 = 31472846
397 + 31472449 = 31472846
409 + 31472437 = 31472846
487 + 31472359 = 31472846
607 + 31472239 = 31472846

Showing the first eight; more decompositions exist.
