Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448348, here are decompositions:

67 + 31448281 = 31448348
157 + 31448191 = 31448348
199 + 31448149 = 31448348
277 + 31448071 = 31448348
331 + 31448017 = 31448348
397 + 31447951 = 31448348
691 + 31447657 = 31448348
907 + 31447441 = 31448348

Showing the first eight; more decompositions exist.
