Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480248, here are decompositions:

47 + 31480201 = 31480248
131 + 31480117 = 31480248
157 + 31480091 = 31480248
199 + 31480049 = 31480248
227 + 31480021 = 31480248
229 + 31480019 = 31480248
367 + 31479881 = 31480248
419 + 31479829 = 31480248

Showing the first eight; more decompositions exist.
