Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130442, here are decompositions:

3 + 130439 = 130442
19 + 130423 = 130442
31 + 130411 = 130442
43 + 130399 = 130442
73 + 130369 = 130442
79 + 130363 = 130442
139 + 130303 = 130442
163 + 130279 = 130442

Showing the first eight; more decompositions exist.
