Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499054, here are decompositions:

31 + 31499023 = 31499054
61 + 31498993 = 31499054
157 + 31498897 = 31499054
241 + 31498813 = 31499054
313 + 31498741 = 31499054
397 + 31498657 = 31499054
463 + 31498591 = 31499054
541 + 31498513 = 31499054

Showing the first eight; more decompositions exist.
