Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479854, here are decompositions:

37 + 31479817 = 31479854
61 + 31479793 = 31479854
97 + 31479757 = 31479854
157 + 31479697 = 31479854
277 + 31479577 = 31479854
313 + 31479541 = 31479854
337 + 31479517 = 31479854
397 + 31479457 = 31479854

Showing the first eight; more decompositions exist.
