Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479446, here are decompositions:

7 + 31479439 = 31479446
109 + 31479337 = 31479446
139 + 31479307 = 31479446
157 + 31479289 = 31479446
373 + 31479073 = 31479446
463 + 31478983 = 31479446
487 + 31478959 = 31479446
709 + 31478737 = 31479446

Showing the first eight; more decompositions exist.
