Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461302, here are decompositions:

73 + 31461229 = 31461302
79 + 31461223 = 31461302
109 + 31461193 = 31461302
139 + 31461163 = 31461302
331 + 31460971 = 31461302
373 + 31460929 = 31461302
463 + 31460839 = 31461302
601 + 31460701 = 31461302

Showing the first eight; more decompositions exist.
