Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479524, here are decompositions:

7 + 31479517 = 31479524
67 + 31479457 = 31479524
103 + 31479421 = 31479524
283 + 31479241 = 31479524
397 + 31479127 = 31479524
463 + 31479061 = 31479524
523 + 31479001 = 31479524
541 + 31478983 = 31479524

Showing the first eight; more decompositions exist.
