Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479044, here are decompositions:

13 + 31479031 = 31479044
43 + 31479001 = 31479044
61 + 31478983 = 31479044
193 + 31478851 = 31479044
307 + 31478737 = 31479044
397 + 31478647 = 31479044
463 + 31478581 = 31479044
523 + 31478521 = 31479044

Showing the first eight; more decompositions exist.
