Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487148, here are decompositions:

37 + 487111 = 487148
97 + 487051 = 487148
127 + 487021 = 487148
157 + 486991 = 487148
199 + 486949 = 487148
241 + 486907 = 487148
331 + 486817 = 487148
367 + 486781 = 487148

Showing the first eight; more decompositions exist.
